Clarence Douglas "Clare" McKerrow (January 18, 1877 – October 20, 1959) was a Canadian athlete.

McKerrow competed in lacrosse for Canada in the 1908 Summer Olympics.

But when Billy Barlow was absent for the March 9, 1895, Stanley Cup challenge game against the Queen's University team of the OHA, McKerrow was called upon to play, scoring a goal while his team defended the Stanley Cup, and from there on he was a fixture on the team roster.

[3] In March 1902, McKerrow coached the Montreal Hockey Club, then dubbed the "Little Men of Iron" because of the small stature of many of its players (including Dickie Boon, Archie Hooper, Jimmy Gardner and Jack Marshall), to a Stanley Cup victory over the Winnipeg Victorias.

[4] In 1908 he was part of the Canadian lacrosse team which won the gold medal in the Summer Olympics, alongside future ice hockey magnate Tommy Gorman.
