2023 All-Ireland Senior Football Championship
The 2023 All-Ireland Senior Football Championship was the 137th edition of the Gaelic Athletic Association's premier inter-county Gaelic football tournament since its establishment in 1887. Thirty one of the thirty two Irish counties took part – Kilkenny did not compete, while London and New York completed the lineup.
The championship worked as a two-tier system for the second time, with the Tailteann Cup being the second tier competition for those that do not qualify for the Sam Maguire Cup competition.
The draws for the provincial championships took place on 15 October 2022. The final was played on 30 July 2023 at Croke Park in Dublin, between defending champion Kerry and Leinster champion Dublin. Dublin won a 31st title, with a 1–15 to 1–13 win against Kerry in that game.
Format
Provincial Championships
Connacht, Leinster, Munster and Ulster each organise a provincial championship. All provincial matches are knock-out.Group stage format
Sixteen teams progress to the All-Ireland Championship round-robin:- The 4 provincial champions
- The 4 beaten provincial finalists
- The 2022 Tailteann Cup winners
- The 7 next-ranked teams, based on final position in the 2023 National Football League
- * Position is based on standing after promotion and relegation are applied and after finals are played; therefore, the top two teams in Division 2 outrank the bottom two teams in Division 1, and if the 2nd placed team in Division 2 wins the final, they are ranked above the 1st place finishers who lost the final.
- * If Westmeath reach the Leinster final, then an 8th team will be chosen based on league position.
In the All-Ireland Championship round-robin, 16 teams are drawn into four groups of four teams. Each team plays the other teams in its group once, earning 2 points for a win and 1 for a draw. Each team plays one home, one away and one neutral fixture.
The top three in each group advance to the knockout stages; first-place teams to the All-Ireland quarter-finals, and second- and third-placed teams to the preliminary quarter-finals.
All-Ireland format
The four second-placed teams play against the third-placed teams in the preliminary quarter-finals. The winners of the preliminary quarter-finals advance to play the group winners in the All-Ireland quarter-finals. Two semi-finals and a final follow. All matches are knock-out.Teams by province

Incidents
Armagh v Monaghan quarter-final
During the All-Ireland quarter-final clash between Armagh and Monaghan, Gardaí arrested seven people and 15 fans were ejected from Croke Park after a fight broke out on Hill 16 before the penalty shoot-out. Video footage later emerged on social media showing blows being exchanged between Armagh and Monaghan fans and some of those involved being knocked to the ground. The footage was condemned by the GAA, saying it represented "unacceptable behaviour from a small number of supporters", warning fans that Hill 16 could be converted to seats if fighting in the terraced stand continued.Earlier in the match, the Hawk-Eye score detection system malfunctioned again after it returned a 'data unavailable' message. The GAA requested an explanation from Hawk-Eye who concluded that the message was a result of operator error. The next day the GAA took the decision to stand down Hawk-Eye once again.
