Harry Hemming Cornish (19 February 1871 – 24 October 1918) was an English cricketer. Cornish's batting and bowling styles are unknown. The son of James Cornish and Fanny Hemming, he was born in St James's Park, London.^[1]

Cornish made a single first-class appearance for Middlesex in 1893 against the touring Australians.^[2] In the Australians first-innings, he bowled 3 wicket-less overs.

In the Australians second-innings, he bowled 2 further wicket-less overs, while in the Middlesex second-innings, he scored 6 runs before being dismissed by George Giffen.^[3]

Two years later he married Florence Gwatkin, before later emigrating to the United States. His marriage to Florence must have ended in divorce, because 5 years later he married a woman called Dorethy in the United States. They had one son, Richard V. C.
