The season featured eighteen clubs, ran from 23 March until 30 September, and comprised a 22-game home-and-away season followed by a finals series featuring the top eight clubs.
The premiership was won by the Richmond Football Club for the eleventh time, after it defeated Adelaide by 48 points in the 2017 AFL Grand Final.
