Brendan Devenney (born 1976) is an Irish Gaelic football coach, broadcaster and former player. He played his club football for St Eunan's and also represented the Donegal county team and won the 1998 and 2001 International Rules Series with Ireland. Of a mercurial temperament, Devenney often wandered away from the sport to play association football instead. Described by RTÉ as "one of the greatest players to have worn the Donegal jersey", Devenney was his county's "main marksman in the pre-McGuinness era".
