François Baby (December 16, 1768 – August 27, 1852) was a French-Canadian businessman, soldier, and politician in Upper Canada.
He was based in Detroit when it was still under the control of Great Britain and before it was ceded to the newly independent United States.
A French Canadian Roman Catholic, Baby belonged to one of the richest and most powerful families in the Western District of Upper Canada at that time.
In 1792, he was elected to represent Kent County (now Ontario) in the first Legislative Assembly of Upper Canada.
During the war, Baby's newly constructed house at Sandwich (Windsor) was taken over by invading American troops.
