Harold Clifford "Harry" Hatch (1884–1946) was a millionaire industrialist from Prince Edward County, Ontario, specializing in the business of wine and spirits.

Hatch started out with a small liquor store in Whitby, Ontario, and prospered to the point where he was able to purchase the controlling interest of Gooderham & Worts Ltd. in 1923.

At that time Canadian wineries typically made only ports and sherries, but Hatch pursued the development of a dry table wine and invested company resources into experimenting with different grape varieties not traditionally found in Niagara.

A horse he imported from Argentina, Filisteo, set an American record in 1941 in the Exterminator Handicap at Pimlico and later sired Plate winner Collisteo.

Harry Hatch was buried in Deseronto, Ontario, the town where he attended school and first worked (in his father's hotel).
