Eric Mackenzie Robertson (12 September 1892 – 28 July 1975) was a Newfoundland marathoner, who competed at the 1920 Summer Olympics in Antwerp, Belgium for Great Britain.
While working in a clothing store some of his co-workers were members of the Polytechnic Harriers, and through them he developed his love of running.
In 1920, he travelled to Antwerp to cheer on his teammates from the Harriers, who were members of the British team.
However, the British team was short one person and his teammates convinced their coach to let Robertson run in the marathon.
