# 2004 All-Ireland Senior Football Championship

The 2004 All-Ireland Senior Football Championship, known for sponsorship reasons as the 2004 Bank of Ireland All-Ireland Senior Football Championship was the premier Gaelic football competition in 2005. It consisted of 33 teams and began on Sunday 2 May 2004. The championship concluded on Sunday 26 September 2004, when Mayo were defeated by Kerry by 1–20 to 2–9.

## Format

Since the introduction of the so-called "back-door" system, a number of changes have taken place in the championship format. In 2004 the following system was used:
The provincial championships in Munster, Leinster, Ulster and Connacht ran 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 do not qualify for the Provincial Semifinals. An open draw was made to give eight pairings.
* Round 2 consisted of the eight defeated teams in the Provincial Semifinals 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 each of the four teams defeated in the Provincial Finals playing against the four winners from Round 3. A draw was made to determine the four pairings.
The All-Ireland Quarterfinals: Each of the four Provincial Champions played one of the four winners from Round 4. The All-Ireland Semifinals were on a Provincial rota basis, initially determined by the Central Council. If a Provincial Championship winning was defeated in its Quarterfinal, the team that defeated it would take its place in the semifinal.
