|Leading Goalkicker Medallist||Dick Lee (Collingwood)|
The 1917 VFL season was the 21st season of the Victorian Football League (VFL), the highest level senior Australian rules football competition in Victoria.
Played during the latter stages World War I, only six of the league's nine senior clubs competed, with Geelong and South Melbourne returning after being in recess the previous year. The season ran from 12 May until 22 September, and comprised a 15-game home-and-away season followed by a finals series featuring the top four clubs.
The premiership was won by the Collingwood Football Club for the fourth time, after it defeated Fitzroy by 35 points in the 1917 VFL Grand Final.
In 1917, the VFL competition consisted of six teams of 18 on-the-field players each, with no "reserves", although any of the 18 players who had left the playing field for any reason could later resume their place on the field at any time during the match.
Each of the six teams played each other three times in a 15 match home-and-away season (Geelong, Richmond, and South Melbourne each hosting eight games, while Carlton, Collingwood, and Fitzroy each hosted seven).
Once the 15 round home-and-away season had finished, the 1917 VFL Premiers were determined by the specific format and conventions of the amended "Argus system".
