The Hamilton Amateur Athletic Association Grounds (also known as the Hamilton AAA Grounds) is a park located on the north side of Charlton Avenue West,between Locke Street South and Queen Street South, in Hamilton, Ontario, Canada. The park served as home to the Hamilton Tigers from 1872-1949. In 1950, the Tigers amalgamated with the Hamilton Wildcats to create the Hamilton Tiger-Cats. The new team became the permanent tenants of Ivor Wynne Stadium, and still plays their home games there today. The Tiger-Cats joined the Canadian Football League as an inaugural member in 1958. A plaque outlining much of the Grounds history (including information on the Grey Cup games played there) is located next to the main entrance on Charlton.
