Sixteen teams compete with the winner representing Mayo in the Connacht Senior Club Football Championship.
Castlebar Mitchels were the defending champions after they defeated rivals Breaffy in the 2015 final.
They successfully defended their title to claim a "2-in-a-row" and their 30th overall when they defeated Knockmore 3-13 to 0-10 in McHale Park on 29 October 2016.
This year Hollymount-Carramore made their debut in the senior grade after just 6 seasons in existence since the amalgamation of the Hollymount and Carramore clubs in 2011 when claiming the Mayo Intermediate Football Championship title.
Carramore's greatest achievement came in 1982 when they beat Glenamoy in the county junior final on a unique scoreline of 0-4 to 0-0.
