The 1965 All-Ireland Senior Football Championship was the 79th staging of the All-Ireland Senior Football Championship, the Gaelic Athletic Association's premier inter-county Gaelic football tournament. The championship began on 2 May 1965 and ended on 26 September 1965.
Limerick rejoin the Munster football championship for the first time since 1952.
The decider was a repeat of the 1964 All-Ireland Senior Football Championship Final, between Galway and Kerry. There was no change in the outcome as Galway defeated Kerry again by 0-12 to 0-09. It was Galway’s second title in succession, on their way to "Three In A Row".
The Connacht championship, instead of the normal system, has two quarter-finals and one semi-final instead of the usual one quarter-final and two semi-finals for just one year. All-Ireland champions Galway received a bye to the Connacht final meaning that Mayo, Roscommon, Sligo and Leitrim would be in separate quarter-finals. The winners of the two games would play in a lone semi-final while the semi-final winner would play Galway.
The only year in between (1933-1940) & 2020 that it happened.
The Leinster championship dropped the second round after one year in 1965. The preliminary round winners went on to the quarter-finals.
