1998 All-Ireland Senior Football Championship

The 1998 Bank of Ireland All-Ireland Senior Football Championship was the 112th edition of the GAA's premier Gaelic football competition. The championship began on 3 May 1998 and ended on 27 September 1998.

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. This was Galway's eighth All-Ireland triumph in all. Kildare, managed by Mick O'Dwyer, had defeated the 1995 champions Dublin and the 1996 champions Meath to win their first Leinster title since 1956, before defeating the 1997 champions Kerry in the All-Ireland semi-final.
