Brendan Devenney (born 1976) is an Irish Gaelic football coach, broadcaster and former player.

Devenney played for the St Eunan's club, and also represented the Donegal county team.

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".

[5] In the final of the 1999 Donegal Senior Football Championship, Devenney broke Martin McHugh's record by scoring 0–14 of his team's 1–19 to their opponents Aodh Ruadh's 1–11.

He ignored his injury, sustained in the first half, and carried on until the end of the game—scoring four points and contributing to the decisive goal which won the game for his team—after which he was hospitalised.

[3] His debut against Cork in the National Football League quarter-final at Croke Park in March 1998 was nothing short of sensational: he scored 2–2.

[2] He played in his first Ulster Senior Football Championship final later that year, and though he lost, he received the man of the match award.

[2] He played in the 2003 All-Ireland Senior Football Championship semi-final against Armagh, scoring three points (all of which were frees).

[2] That year, Devenney contributed to the county winning its first National Football League title in 2007, passing a late fitness test to play in the final against Mayo.

[15][16] He made a substitute appearance against Armagh in the 2007 Ulster SFC quarter-final at MacCumhaill Park on 27 May that year and scored the last-minute goal which defeated the Orchard County by a single point on a scoreline of 1–9 to 1–8.

You look at Bernard and Alan Brogan against Dublin in that [All-Ireland] semi-final a couple of years ago.

[21] He scored four overs in the first test, held at the Melbourne Cricket Ground on 12 October, as Ireland won 59–53.

Devenney, however, was not sufficiently interested in the sport to take up an offer of a two-year contract with Finn Harps in 2007, preferring to play football for Donegal.

[11] He predicted Derry would beat Donegal in the 2014 Ulster Senior Football Championship quarter-final.

[28] On 10 February 2020, a weekly programme called DL Debate began airing on Highland Radio.

[29] Devenney's guests on the first episode included John Haran, Colm Parkinson (Laois) and Ciarán Whelan (Dublin).

[30] Others in later episodes included Neil Gallagher, John Gildea, Enda McGinley (Tyrone), Rory Kavanagh, Donal Reid, Bernard Flynn (Meath), P. J. McGowan and David Brady (Mayo).

[33][34] "DV's Charity Ball", as it was termed, was held in November 2021 at Letterkenny's Mount Errigal Hotel.

[35] Devenney said his second ball would involve a drinks reception, four-course meal, an auction and music.
