Joseph F.W. DesBarres (November 22, 1721 - October 27, 1824) was a Swiss-born cartographer and Canadian statesman, who served as aide-de-camp to General James Wolfe in Quebec.

DesBarres made many maps of the Atlantic, Pacific and Indian oceans and also mapped much of the Canadian Territory, most notably Nova Scotia and its capital Halifax.

DesBarres was also the Governor of Prince Edward Island, from about 1804-1806.

He died at the age of 102, and his date of death is variously given as October 27 and October 24.
