The Ross Glendinning Medal is awarded to the player judged best on ground in the Western Derby football match played between Fremantle Football Club and the West Coast Eagles.
It is named after and awarded by former Western Australian footballer Ross Glendinning, who was the inaugural captain of the West Coast Eagles and is a former Fremantle chairman of selectors. It is voted by Glendinning and a selection of media representatives. Joint medals are presented in the event of more than one player finishing with the equal-highest number of votes.
Fremantle's Paul Hasleby has currently won the medal 4 times, the most by any player.
