The GAA is very strong in the community. Thanks to extensive volunteer work and generous local support and sponsorship Knocknagree GAA club can boast of having one of the best venues in the area. The main pitch was professionally floodlit in 2006. In 2007 it hosted the first Duhallow Junior A Football Championship final to be played under lights. Ballydemond were victorious over Dromtarriffe on the occasion.
The club crest was designed in 2002 by a local artist. It features a horse's head superimposed against a hill. A traditional Irish fiddle is in the left upper corner and an open book in the right upper corner. These are reminders of Knocknagree's musical and literary heritage. A Blackwater bridge is featured in the lower foreground to symbolise the club's border location. Significantly the leaping salmon faces the Cork side of the border.Knocknagree also have great under aged teams in the last two years in a row there under 12 team have made to a Duhallow final they might have been beaten every time but being the underdogs twice they put on a great show that made everyone in knocknagree proud.
