Supplement Dated August 24, 2020, to the Prospectus and Summary Prospectus Dated February 27, 2020

Restructuring of the Investment Advisory Team

The Board of Trustees of Vanguard Whitehall Funds, on behalf of Vanguard International Explorer Fund (the Fund), has approved a restructuring of the Fund's investment advisory team, adding Baillie Gifford Overseas Limited (Baillie Gifford) as a new investment advisor to the Fund.

The Fund operates under the terms of an SEC exemption, whereby the Fund's Board of Trustees may, without prior approval from shareholders, hire a new advisor.

Effective immediately, Baillie Gifford manages a portion of the Fund's assets along with the Fund's existing advisors. Each advisor independently selects and maintains a portfolio of common stocks for the Fund. The Fund's Board of Trustees determines the proportion of the Fund's assets to be managed by each advisor and may change these proportions at any time.

In connection with the addition of Baillie Gifford to the Fund, effective immediately, Brian Lum and Stephen Vaughan are added as co-portfolio managers of the Baillie Gifford portion of the Fund.

Also effective immediately, the following other changes to the Fund's investment advisors are made:

Mary L. Pryshlak, who leads Wellington Management Company LLP's (Wellington Management) International Small Cap Research Equity team, is added as a portfolio manager of the Wellington Management portion of the Fund. She replaces Simon Thomas, who led the International Small Cap Equity team managing Wellington Management's portion of the Fund since 2010. Mr. Thomas is removed as a portfolio manager of the Fund, and all references to Mr. Thomas and corresponding disclosure related to Mr. Thomas in the Fund's Prospectus and Summary Prospectus are hereby deleted.

Luke Biermann is added as a co-portfolio manager for Schroder Investment Management North America Inc.'s (Schroders) portion of the Fund, joining existing Schroders portfolio manager Matthew Dobbs who will be retiring from that role at the end of March 2021.

The Fund's investment objective, principal investment strategies, and policies remain unchanged.

Prospectus Text Changes

In the More on the Fund section, the following is added to the list of advisors under the "Security Selection" heading on page 8:

Baillie Gifford follows an investment approach based on making long-term investments in well-researched and well-managed businesses with above-average growth potential. Baillie Gifford analyzes a company's ability to grow at an above-average rate by considering the industry in which it operates, any sustainable competitive advantages the company has within that industry, the ability of management to execute on the market opportunity before them, and whether the company can fund growth with internally generated cash flows. Baillie Gifford also considers the valuation of the company to understand the extent to which the market has already appreciated these factors. Historically, Baillie Gifford has been willing to pay a premium for companies it believes can deliver superior growth.

In the same section, the following replaces in its entirety similar text on page 9 for Wellington Management:

Wellington Management allocates assets to a team of Wellington Management investment professionals who are primarily Global Industry Analysts (GIAs). The relative size of each analyst's sub-portfolio of assets is roughly proportionate to the relative weight of the analyst's coverage universe in the MSCI EAFE Small Cap Index.

Wellington Management employs a bottom-up approach that seeks to add value through in-depth fundamental research and understanding of its industries. Wellington Management believes that the experience of covering the same companies over a period of many years provides the GIAs with in-depth knowledge of their coverage, which in turn leads to better and more timely decisions and increases their potential to produce superior results. The strategy combines a blend of investment disciplines, which diversifies investment style risk, as individual analysts have developed valuation methodologies that have proved most relevant to their particular industries. The country weights are determined by the stock selection process.

The following is added as an additional bullet to the list of investment advisors under the "Investment Advisors" heading beginning on page 14:
