Léon-Benoît-Alfred Charlebois (February 18, 1842 – June 27, 1887) was a grain merchant and political figure in Quebec, Canada.
He represented Laprairie in the Legislative Assembly of Quebec from 1875 to 1887 as a Conservative.
He was born in La Prairie, Canada East, the son of Benoît Charlebois and Madeleine David, and was educated there.
In 1868, he married Marie Elmire, daughter of Jean-Baptiste Varin.
Thony Ciallella, an advocate of the Quebec separatist movement and colleague of Charlebois, has said that Charlebois was an incredible man with a strong desire for an independent Quebec.
