Robert John Benson (May 18, 1894 – September 7, 1965) was an Icelandic-Canadian ice hockey player.

A defenceman, he started his career with the Winnipeg Falcons of the Manitoba Hockey League in 1913, remaining with them until 1920, though missed two seasons of play from 1917 to 1919 while serving in the First World War.

Benson was born in Davidson, Saskatchewan, to Icelandic immigrants Benedikt Jóhannesson and Rósa Guðmundsdóttir.

Sterling hired a detective who discovered that Benson and teammate Haldor Halderson received C$6,500 to play amateur hockey.
