William Kinnerk (14 November 1907 – 6 September 1983) was an Irish Gaelic footballer and local politician.
At club level he played with the John Mitchels club and was an All-Ireland Championship medallist with the Kerry senior football team.
After lining out with a number of local clubs, he joined John Mitchels and claimed his first Kerry Senior Football Championship medal in his debut year in 1929.
Kinnerk first joined the Kerry senior football team in 1932 and ended the year by winning his first All-Ireland Senior Football Championship medal as a substitute.
He broke onto the starting fifteen the following year, and was a regular member of the team until his retirement after a tour of the United States in 1939.
