The 1921 Victorian Football Association season was the 43rd season of the Australian rules football competition.
The premiership was won by the Williamstown Football Club, after it came from fourth on the home-and-home ladder to defeat minor premiers Footscray by 18 points in the Grand Final, played very late in the year on 22 October. It was the club's second VFA premiership.
The season was disrupted when the North Melbourne Football Club abruptly disbanded at midseason, a consequence of wide-ranging off-field manoeuvres in both the VFA and the VFL, which stemmed from the closure the East Melbourne Cricket Ground.
