The first mention of Portumna in terms of Gaelic games comes in 1888 with regard to a junior Gaelic football game against Eyrecourt. The club remained in the background of senior club hurling until 1995 when Portumna contested their first county final. Victory on that occasion went to Sarsfield's. The 2000s saw a golden age for the club as it contested seven consecutive county finals between 2003 and 2009. Victory was achieved in 2003, 2005, 2007, 2008 and 2009. Portumna also won three All-Ireland titles during this period (2006, 2008 and 2009) as well as in returning to win in 2014. A book on the history of the club titled ‘Hearts of Oak the rise to glory of Portumna GAA club’, written by historian John Joe Conwell, has been published by the club.
