Charles Champagne (French pronunciation: [ʃaʁl ʃɑ̃paɲ]; July 25, 1849 – September 21, 1925) was a lawyer and a political figure in Quebec.
He represented Hochelaga in the Legislative Assembly of Quebec from 1888 to 1890 as a Liberal.
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 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.
