Charles Champagne (July 25, 1849 – September 21, 1925) was a lawyer and political figure in Quebec.
He represented Hochelaga in the Legislative Assembly of Quebec from 1888 to 1890 as a Liberal.
His name also appears as Charles Laplante dit Champagne.
He was born in Saint-Augustin, Canada East, the son of Charles Laplante dit Champagne and Marie Brien dit Desrochers.
For a time, Champagne served as the personal secretary for Louis Riel.
He was admitted to the Quebec bar in 1873 and set up practice in Sainte-Scholastique.
Champagne was married twice: to Mary Jessey Fletcher in 1873 and to Mary Louisa Fletcher, his first wife's sister, in 1883.
Champagne was an unsuccessful candidate for the Hochelaga electoral district in 1886, losing to Joseph-Octave Villeneuve, but was elected in an 1888 by-election held after Villeneuve's election was appealed.
He was defeated by Villeneuve when he ran for reelection in 1890.
