	Know all men by these presents, that I, Mary Jo Dively, 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
amendments to said reports, incorporating such changes as said attorneys-in-fact

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 Sixth day
