The 1990 AFL season was the 94th season of the Australian Football League (AFL) and the first under this name, having been known as the Victorian Football League until 1989.
It was the highest level senior Australian rules football competition and administrative body in Victoria; and, as it featured clubs from New South Wales, Queensland and Western Australia, it was the de facto highest level senior competition in Australia.
The season featured fourteen clubs, ran from 31 March until 6 October, and comprised a 22-game home-and-away season followed by a finals series featuring the top five clubs.
The premiership was won by the Collingwood Football Club for the 14th time, after it defeated Essendon by 48 points in the 1990 AFL Grand Final.
Essendon defeated North Melbourne 17.10 (112) to 10.16 (76) in the final.
