The 1945 All-Ireland Senior Football Championship was the 59th staging of the All-Ireland Senior Football Championship, the Gaelic Athletic Association's premier inter-county Gaelic football tournament. It was played at venues all over Ireland from 29 April to 23 September 1945.
31 teams entered, with Kilkenny once again declining to field a team. Roscommon were the defending champions, however, they surrendered their title in their opening game, a Connacht semi-final defeat by Mayo.
The All-Ireland final was played on 23 September 1945 at Croke Park in Dublin, between Cork and Cavan, in what was their first ever meeting in a final. Cork won the match by 2âÂÂ05 to 0âÂÂ07 to claim their third championship title overall and a first title since 1911.
