Charles Henry Margrett (10 August 1862 – 22 November 1941) was an English cricketer. Margrett's batting style is unknown. He was born at Cheltenham, Gloucestershire.
Margrett made a single first-class appearance for Gloucestershire against Sussex in 1886 at the County Ground, Hove. Gloucestershire made 147 in their first-innings, with Margrett scoring 14 runs before he was dismissed by Jesse Hide. In response, Sussex made 349 in their first-innings, which Gloucestershire responded to in their second-innings by making 219, during which Margrett was dismissed for a duck by Walter Humphreys. Needing just 18 to win, Sussex reached their target without losing a wicket. This was his only major appearance for Gloucestershire.
He died at the town of his birth on 22 November 1941.
