1980 All-Ireland Senior Football Championship

The 1980 All-Ireland Senior Football Championship was the 94th staging of the All-Ireland Senior Football Championship, the Gaelic Athletic Association's premier inter-county Gaelic football tournament. The championship began on 11 May 1980 and ended on 21 September 1980.

Kerry entered the championship as the defending champions.

On 21 September 1980, Kerry won the championship following a 1-9 to 1-6 defeat of Roscommon in the All-Ireland final. This was their 26th All-Ireland title and their third in succession.

Offaly's Matt Connor was the championship's top scorer with 5-31. Kerry's Jack O'Shea was named as the Texaco Footballer of the Year.

Munster Championship format change
Following a number of one-sided results in the Munster Championship in the late 1970s, the Munster Council changed the format in 1980. Kerry, long regarded as the standard bearers in the province, were given a bye to the Munster final. Cork, who had been second to Kerry since 1975, were given a bye to a lone semi-final. The other four "weaker" teams (Clare, Limerick, Tipperary and Waterford) were paired against each other in two preliminary round games. The winners of these two games faced each other in a lone quarter-final with the winners of that game qualifying to meet Cork in the lone semi-final. This format was previously used in 1941 and lasted only one season.
