Bunaíodh Cumann Peile Acla faoi bhrat an Pharráiste i 1941, agus comhthogadh é sa ghrád sóisir ar Bord Mhuigheo C.L.C.G. I 1942 bhuaigh an club craobh Mhuigheo Thiar agus craobh an chondae. Is mór an forfhás a tháinig ar an chlub ó shoin.

The Achill GAA Club was officially established and affiliated to the Mayo County Board in 1941. Although the area was not new to Gaelic games, there never existed a club as such to bring together the footballers of the numerous villages to play as one team and represent the parish itself. The Junior footballers contested their first ever West Mayo Championship in 1942 and not only did they win that, they also proceeded to capture the County title.
