Summary of Significant Accounting Policies (Policies)	Jun. 30, 2016
Accounting Policies [Abstract]
Nature of Operations	Nature of Operations Effective November 1, 2013, Riverview and Union Bancorp, Inc. (“Union”) consolidated to form a new Pennsylvania corporation under the name of Riverview Financial Corporation (the “Company”). Riverview Bank (the “Bank”) is the wholly-owned subsidiary of the Company. Effective December 31, 2015, The Citizens National Bank of Meyersdale (“Citizens”) merged with and into Riverview Bank, with Riverview Bank surviving. The balance sheet as of December 31, 2015, includes the former Citizens’ assets and liabilities. The Company’s financial results reflect the consolidation of Riverview and Union with and into Riverview Bank and the merger of Citizens with and into Riverview Bank under the purchase method of accounting, with the Company treated as the acquirer from an accounting standpoint. In the case of the consolidation of Riverview and Union, the Company was formed and treated as a recapitalization of Riverview, with Riverview’s assets and liabilities recorded at their historical values, and Union’s assets and liabilities recorded at their fair values as of the effective date of the consolidation. The Bank is a Pennsylvania state chartered bank. The Company and the Bank are subject to regulation by certain state and federal agencies. These regulatory agencies periodically examine the Company and the Bank for adherence to laws and regulations. The accounting and reporting policies followed by the Company conform to generally accepted accounting principles and to general practices within the banking industry. The following paragraphs briefly describe the more significant accounting policies.
Principles of Consolidation and Basis of Accounting	Principles of Consolidation and Basis of Accounting The Company’s unaudited consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, the Bank and its operating divisions, Marysville Bank, Halifax Bank, Citizens Neighborhood Bank and Riverview Financial Wealth Management. All significant intercompany accounts and transactions have been eliminated in consolidation. The Company uses the accrual basis of accounting. The Company’s unaudited financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and predominant practices within the banking industry, and are presented in accordance with instructions for Form 10-Q and Rule 10-01 of Securities and Exchange Commission Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation are of a normal and recurring nature and have been included. Operating results for the three and six months ended June 30, 2016 are not necessarily indicative of the results that may be expected for the year ended December 31, 2016 or any other future period. The consolidated financial statements presented in this report should be read in conjunction with the audited consolidated financial statements and the accompanying notes for the year ended December 31, 2015, included in the Company’s Form 10-K, filed with the Securities and Exchange Commission on March 30, 2016.
Use of Estimates	Use of Estimates These consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) and predominant practices within the banking industry. The preparation of these consolidated financial statements requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. The Company evaluates estimates on an ongoing basis. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the potential impairment of goodwill, the valuation of deferred tax assets, the determination of other-than-temporary impairment on securities and the valuation of real estate acquired by foreclosure or in satisfaction of loans. The determination of the adequacy of the allowance for loan losses is based on estimates that are particularly affected by significant changes in the economic environment and market conditions. In connection with the determination of the estimated losses on loans and foreclosed real estate, management obtains independent appraisals of the value of significant collateral. While management uses available information to recognize losses on loans, further reductions in the carrying amounts of loans may be necessary based on changes in local economic conditions. In addition, regulatory agencies, as an integral part of their examination process, periodically review the estimated losses on loans. Such agencies may require the Bank to recognize additional losses based on their judgments about information available to them at the time of their examination. Because of these factors, it is reasonably possible that the estimated losses on loans may change materially in the near term. However, the amount of any such change cannot be estimated.
Accounting Policies	Accounting Policies The accounting policies of the Company as applied in the interim consolidated financial statements presented, are substantially the same as those followed on an annual basis, as applied in the Company’s annual consolidated audited financial statements included in the Company’s Form 10-K. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for Riverview Financial Corporation for the year ended December 31, 2015. The results of interim periods presented are not necessarily indicative of the results that may be expected for the year ending December 31, 2016.
Segment Reporting	Segment Reporting The Company operates in a single business segment consisting of traditional banking activities.
Subsequent Events	Subsequent Events Generally accepted accounting principles establish general standards for accounting for and disclosure of events that occur after the balance sheet date but before the financial statements are issued. In preparing these consolidated financial statements, the Company evaluated the events and transactions that occurred from the date of the financial statements through August 12, 2016, the date this Form 10-Q was filed, and has not identified any events, that require recognition or disclosure in the consolidated financial statements.
Recent Accounting Pronouncements	In August 2015, the FASB issued ASU No. 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of Effective Date”. The amendments in ASU 2015-14 defer the effective date of ASU 2014-09 for all entities by one year. Public business entities, certain not-for-profit entities, and certain employee benefit plans should apply the guidance in ASU 2014-09 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. All other entities should apply the guidance in ASU 2014-09 to annual reporting periods beginning after December 15, 2018, and interim reporting periods within annual reporting periods beginning after December 15, 2019. All other entities may apply the guidance in ASU 2014-09 earlier as of an annual reporting period beginning after December 15, 2016, including interim reporting periods within that reporting period. All other entities also may apply the guidance in ASU 2014-09 earlier as of an annual reporting period beginning after December 15, 2016, and interim reporting periods within annual reporting periods beginning one year after the annual reporting period in which the entity first applies the guidance in ASU 2014-09. The Company is currently assessing the impact that ASU 2015-14 (or ASU 2014-19) will have on its consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, “Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.” The amendments in ASU 2016-01, among other things: (1) Requires equity investments (expect those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income; (2) Requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; (3) Requires separate presentation of financial assets and liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables); and (4) Eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost. The amendments in this ASU are effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company is currently assessing the impact that ASU 2016-01 will have on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842).” Among other things, in the amendments in ASU 2016-02, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) A lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) A right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. Certain targeted improvements were made to align, where necessary, lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted upon issuance. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. The Company is currently assessing the impact that ASU 2016-02 will have on its consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-07, “Investments – Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting.” The amendments in this ASU eliminate the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. In addition, the amendments in this ASU require that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. The amendments are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The amendments should be applied prospectively upon their effective date to increases in the level of ownership interest or degree of influence that result in the adoption of the equity method. Early adoption is permitted. The Company does not expect the adoption of ASU 2016-07 to have a material impact on its consolidated financial statements. During March 2016, the FASB issued ASU No. 2016-09, “Compensation – Stock Compensation (Topic 718): Improvements to Employee Shares-Based Payment Accounting”. The amendments in this ASU simplify several aspects of the accounting for share-based payment award transactions including: (1) income tax consequences; (2) classification of awards as either equity or liabilities; and (3) classification on the statement of cash flows. The amendments are effective for public companies for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The Company is currently assessing the impact that ASU 2016-09 will have on its consolidated financial statements. During June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”. The amendments in this ASU, among other things, require the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses. In addition, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The amendments in this ASU are effective for SEC filers for years, and intermit periods within those fiscal years, beginning after December 15, 2019. For public companies that are not SEC filers, the amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. The Company is currently assessing the impact that ASU 2016-13 will have on its consolidated financial statements.
