The Laois Senior Football Championship is an annual Gaelic football competition contested by top-tier Laois GAA clubs. The Laois County Board of the Gaelic Athletic Association has organised it since 1888. Portarlington won the 2024 title, after defeating Portlaoise in the final.

Honours

The trophy presented to the winners is the Jack Delaney Cup. The winners of the Laois Senior Championship qualify to represent their county in the Leinster Senior Club Football Championship. They often do well outside the county, with the likes of Portlaoise (1971, 1976, 1982, 1987, 2004, 2009) among the clubs from Laois to win at least one Leinster Championship after winning the Laois Senior Football Championship. The winners can, in turn, go on to play in the All-Ireland Senior Club Football Championship. In 1982–83, Portlaoise became the first club from Laois to win All-Ireland Senior Football Championship after winning the Leinster and Laois Senior Football Championships.
