The 2013 All-Ireland Senior Football Championship was the 127th edition of the GAA's premier inter-county Gaelic football tournament, played between 31 counties of Ireland (excluding Kilkenny), London and New York. The 2013 All-Ireland Senior Football Championship Final was contested by Dublin and Mayo at Croke Park on 22 September 2013, with Dublin winning by 2:12 to Mayo's 1:14.As It Happened: Dublin secure Sam Maguire RTÉ Sport, 2013-09-22.

Several historic events of note occurred in the 2013 Championship. London won a Connacht Championship game for the first time in 36 years by defeating the Sligo side in the first round of the Connacht Senior Football Championship. They went on to reach the Connacht Final which they lost to Mayo, before progressing to play at Croke Park in a Round 4 All-Ireland Qualifier at which point they exited after the longest Championship run in their history.

Hawk-Eye was introduced for Championship matches at Croke Park and was first used to confirm that Offaly substitute Peter Cunningham's attempted point had gone wide 10 minutes into the second half of a game against Kildare. 2013 also brought the first Friday night game in the history of the Championship – a first round qualifier between Carlow and Laois.

The game of the Championship was the second All-Ireland semi-final, contested by Dublin and Kerry. The game featured six goals, three of which were scored by Kerry in the first half, two of these in the first eleven minutes of the game. Dublin also scored three goals, one in the first half and two in the second half, the second half goals coming in the final moments, to send them through to an All-Ireland final against Mayo, despite having been behind for much of the game. Many people hailed it as the greatest game of the modern era.

Teams A total of 33 teams contested the championship. These included 31 teams from Ireland, as well as London and New York. As in previous years, Kilkenny decided not to field a team.

Format The All-Ireland Senior Football Championship of 2013 was run on a provincial basis as usual. It was a knockout tournament with pairings drawn at random in the respective provinces – there were no seeds.

Referees Ahead of the 2013 Championship, one referee was dropped for his incompetence: Michael Collins, the 2001 All-Ireland final referee, of Cork. Syl Doyle of Wexford had also chosen to step away the previous January. Their replacements were David Gough (Meath), who had refereed the 2013 All-Ireland Under-21 Football Championship final, and Fergal Kelly (Longford).

Pádraig Hughes of Armagh remained injured after running into Eamonn Doherty and collapsing during live play in the NFL Division 1 clash between Donegal and Dublin in Ballybofey. Ciarán Brannigan of Down took the place of Hughes until his return to fitness.
