	Know all men by these presents, that I, Pamela A. Bena, a Director of F.N.B.
Corporation, a corporation organized and existing under the laws of the State of
Pennsylvania, do constitute and appoint James Orie, Scott Free, Vince Calabrese,

any report on Form 3, Form 4, or Form 5, respecting the securities of F.N.B.

together with all exhibits thereto and other documents in connection therewith,
and to sign on my behalf and in my stead, in any and all capacities, any

I acknowledge that I have granted this power of attorney solely to make it more
convenient for me to comply with my reporting responsibilities under Section 16

F.N.B. Corporation nor my attorneys-in-fact have assumed, or shall be deemed to
assumed, any of my responsibilities in that regard.


	IN WITNESS WHEREOF, I have hereunto set my hand and seal this Twenty Seventh
