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 0-12 to 0-9 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 1-48. Armagh forward Steven McDonnell was the choice for the Vodafone Footballer of the Year award. Format 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: Round 1 of the qualifiers included all the counties (except New York) that did not qualify for the Provincial Semi-finals. An open draw was made to give eight pairings. Round 2 consisted of the eight defeated teams in the Provincial Semi-finals playing against the eight winners from Round 1. A draw was made to determine the eight pairings. Round 3 consisted of the eight winners from Round 2. Another open draw was made to determine the four pairings. Round 4 consisted of the four winners from Round 3 playing against the beaten Provincial finalists. A draw was made to determine the pairings. 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.
