The present club was founded in 1982.[6] A teenage Manus McFadden arranged a meeting at Foxhall of Glenswillyites who were interested in forming a team, with John Mc Ginley, Roger McDaid, Fr Eamon Crossan, Finbar Glackin, Jimmy Joe McGinley and chair Eddie McDevitt.[7]
Glenswilly reached their first ever Senior county final in 2007, where they lost to near neighbours St Eunan's 0–12 to 1–3.
On 25 September 2012, the Donegal senior team—fresh from winning the 2012 All-Ireland Senior Football Championship Final—were scheduled to visit Glenswilly; however, the visit was postponed due to time constraints which arose due to the huge crowds around the county eager to catch a glimpse of the team.[11][12][13] The team eventually visited Glenswilly on 27 September.[14][15][16]
In 2013, the club rebuffed allegations that they forced children into GAA jerseys.[4] Later that year they hosted the 2013 All-Ireland Football Series launch, held following confirmation of the four provincial winners.[17][18] That year they won their second Donegal Senior Football Championship and progressed to the final of the Ulster Senior Club Football Championship, which they lost to Ballinderry.[19][20]
The club won its third and final Donegal SFC in 2016.
