The 2003 All-Ireland Senior Football Championship was the 117th staging of the All-Ireland Senior Football Championship, the Gaelic Athletic Association's premier inter-county Gaelic football tournament. The championship began on 4 May 2003 and ended on 28 September 2003.
Armagh entered the championship as the defending champions.
On 28 September 2003, Tyrone won the championship following a 0âÂÂ12 to 0âÂÂ9 defeat of Armagh in the All-Ireland final. This was their first All-Ireland title.
Tyrone's Peter Canavan was the championship's top scorer with 1âÂÂ48. Armagh forward Steven McDonnell was the choice for the Vodafone Footballer of the Year award.
The provincial championships in Munster, Leinster, Ulster and Connacht were run as usual on a "knock-out" basis. These provincial games were then followed by the "Qualifier" system:
The All-Ireland Quarter-finals: Each of the four Provincial Champions played one of the four winners from Round 4. The All-Ireland Semi-finals were played on a Provincial rota basis, initially determined by the Central Council. If a Provincial Championship winning team was defeated in its Quarter-final, the team that defeated it took its place in the semi-final.
