Joseph Willcocks (1773 – September 4, 1814) sometimes spelt Wilcox was a publisher and political figure in Upper Canada. He was elected to the Parliament of Upper Canada in 1807 representing York, 1st Lincoln and Haldimand. He was re-elected twice and frequently opposed government policies. He became disillusioned with Upper Canada after a military rule was introduced to Upper Canada during the War of 1812 and defected to the United States. He was mortally shot on September 4, 1814 at Fort Erie, and buried in Buffalo, New York.
