John Cassin

John Cassin (born 2 July 1951) is a former Australian rules footballer who played for Essendon, North Melbourne and Fitzroy in the VFL, and West Torrens in the SANFL.

He made his league debut in 1971 for Essendon after being recruited by the club under the father-son rule, as his father Jack was a dual premiership player with Essendon.

Cassin was mainly a wingman during his career but was also used on the ball and up forward. In 1975, he left the VFL to join West Torrens in South Australia, where he captained the team for the 1976 season. In 1977 he joined North Melbourne and was one of the club's leading goalkickers in their premiership year with 36 goals. He managed to play every game that year, including the 1977 VFL Grand Final which went to a replay; in doing so, he was the first player to play twenty seven matches in a VFL/AFL season, a record he held uniquely until 2024, after the extension of the home-and-away season to 23 matches. During the 1981 season, he crossed to Fitzroy but appeared only five times for the club before leaving the following year.
