The 1948 VFL season was the 52nd season of the Victorian Football League (VFL), the highest level senior Australian rules football competition in Victoria.

The season featured twelve clubs, ran from 17 April until 9 October, and comprised a 19-game home-and-away season followed by a finals series featuring the top four clubs.

The premiership was won by the Melbourne Football Club for the sixth time, after it defeated Essendon by 39 points in the 1948 VFL Grand Final Replay.

In 1948, the VFL competition consisted of twelve teams of 18 on-the-field players each, plus two substitute players, known as the 19th man and the 20th man.

Once the 19 round home-and-away season had finished, the 1948 VFL Premiers were determined by the specific format and conventions of the Page–McIntyre system.
