The 1998 Bank of Ireland All-Ireland Senior Football Championship was the 112th edition of the GAA's premier Gaelic football competition.

Galway's 1-14 to 1-10 victory over Kildare in the All-Ireland final meant that the Sam Maguire Cup returned to the county and the province of Connacht for the first time since 1966.

The Ulster, Munster, Leinster and Connacht championships were conducted as straight knock-out competitions.

The Munster football championship for the 2nd year running had Kerry, Cork and Clare as byes to the semi-finals while Limerick, Tipperary and Waterford played a lone-first-round game with the bye team in a lone quarter final.

The winners of each provincial competition went on to play in the All Ireland semi-finals.
