William Bent Berczy (January 6, 1791 – December 9, 1873) was a farmer, painter and political figure in Upper Canada.

He was born in London, England in 1791, the son of German immigrants William Berczy and Jeanne-Charlotte Allamand, and came to old York County in Upper Canada with his family in 1794.

He grew up in York (now Toronto) (1794-1798, 1802-1804), Montreal (1798-1802, 1804-1812) and Quebec City (1804-1812) - wherever his father's development work required the family to relocate.

Berczy was lieutenant-colonel in the Lower Canada with the 8th Military District, Canadian Militia unit based in Berthier, Quebec from 1845 to 1863, reaching the rank of colonel.

Two paintings by Berczy hang in the National Gallery of Canada, Huron Indians leaving residence near Amherstburg[1] and Blessing of the Fields.
