The Lou Marsh Trophy, also known as the Lou Marsh Memorial Trophy and Lou Marsh Award, is a trophy that is awarded annually to Canada's top athlete, professional or amateur. It is awarded by a panel of journalists, with the vote taking place in December. It was first awarded in 1936. It is named in honour of Lou Marsh, a prominent Canadian athlete, referee, and former sports editor of the Toronto Star. Marsh died in 1936 and the trophy was named in his honour.
