Harold Marsh "Whiz" Morris (16 April 1898 – 18 November 1984) was an English amateur cricketer. He played for Essex between 1919 and 1932 and was captain of the team between 1929 and 1932. Morris was educated at Repton School, where he captained the First XI, and Cambridge University, where he was unable to find a place in the cricket team. He was a regular member of the Essex side in the 1920s, batting usefully and fielding superbly. In 1927 he scored 143 against Somerset and, a couple of weeks later, 166 against Hampshire, when he added 233 in 140 minutes for the fourth wicket with Jack Russell.
