The Leo Dandurand Trophy is a Canadian Football League trophy awarded to the Most Outstanding Lineman in the East Division. The winner of this trophy is chosen from a group of nominees, one from each team in the East Division. Either the winner of this trophy or the winner of the DeMarco-Becket Memorial Trophy will also receive the Canadian Football League Most Outstanding Offensive Lineman Award. In 1995, as part of the failed American Expansion, this trophy was given to the South Division's Most Outstanding Lineman.
