Joseph-Louis-Euclide Dugas (August 30, 1861 – December 27, 1943) was a farmer and political figure in Quebec.

He represented Montcalm in the House of Commons of Canada from 1891 to 1900 as a Conservative member.

He was born in Montcalm, Canada East, the son of Firmin Dugas, and was educated at the Collège de Joliette and the Collège d'Ottawa.

Dugas' election in 1891 was overturned after an appeal but he won the by-election which followed in 1892.
