Michael Avon (born 23 October 1974) was an Australian rules football field umpire in the Australian Football League.
Avon has umpired the most AFL matches for a South Australian-based Field Umpire with a tally of 179, umpiring his last AFL game in 2010. He umpired the blockbuster Essendon v Collingwood ANZAC Day match in the same year.
In 2011, Avon returned to the South Australian National Football League (SANFL) and in 2012, he umpired his 3rd SANFL Grand Final, alongside Leigh Haussen and Curtis Deboy. Avon had previously umpired the 1996 and 1998 SANFL Grand Finals, a 14 year-gap between his last two finals.
In 2012, Michael umpired his 200th SANFL game in the match between Central District and Glenelg, giving him SANFL Life Membership, This feat was made even more notable given the length of his AFL umpiring career. Avon finished the 2013 season umpiring 2013 SANFL Grand Final again with Haussen and Deboy.
