The Northern Star Award, formerly known as the Lou Marsh Trophy, 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 was named in honour of Lou Marsh, a prominent Canadian athlete, referee, and former sports editor of the Toronto Star. The trophy is made of black marble and stands around 75 centimetres high. The words "With Pick and Shovel" appear above the engraved names of the winners. The voting panel consists of sports media voters from across the country including representatives from the Toronto Star, The Canadian Press, FAN590, The Globe and Mail, CBC, Rogers Sportsnet, CTV/TSN, La Presse and the National Post.

Lewis Edwin Marsh was a Canadian athlete and referee, and one of the pioneers of sports journalism in Canada, working at the Toronto Star for 43 years.
