Castlederg St Eugene's GAC

The club was formed in 1975 under the name Naomh Eoghan Caislean na Deirge and has been in continuous existence ever since.

For the most part of the club's existence they have played their adult football at Junior level. However they were promoted to Intermediate football in 1980 and remained at that level until 1983. They were again successful at gaining promotion in 1989 and stayed in the Intermediate grade until 1993. In 2001 they won their first adult title when their Reserve team annexed the Junior Reserve Championship, beating Newtownstewart at Drumquin.

The senior team competed in Division 3 of the Tyrone All-County Football League and in the Tyrone Junior Football Championship up until they gained promotion in 2016 by finishing top of the League, just a single point above Tattyreagh, after a victory over Glenelly (1-14 to 1–8) on the final day of the season. Unfortunately the club found life in Division 2 difficult, finishing second from bottom with only 8 League points after only 3 league wins and 2 draws.

In 2018 the club returned to junior football, but a string of poor results saw them finish 10th in the league and despite good victories over Killyman and Dregish in the Championship they were unable to progress any further, losing out to Newtownstewart in the quarter-final stage to leave the senior team facing another year in Junior Football.
