Louis François Georges Baby, PC (August 26, 1832 – May 13, 1906) was a Canadian politician and judge.

Born in Montreal, Lower Canada, he first ran for public office in the 1867 federal election in the Quebec riding of Joliette, but lost to François Benjamin Godin.

However, he was unseated by petition protesting the outcome of an election on June 11, 1874.

Baby was a notable collector of Canadian coins, medals, books, and manuscripts.
