Joseph Gauthier (pronounced as /fr/; March 11, 1842[1] - September 26, 1911) was a farmer, grain merchant and political figure in Quebec. He represented L'Assomption in the House of Commons of Canada from 1887 to 1892 and from 1896 to 1900 as a Liberal.
He was born in Saint-Lin, Canada East, the son of Louis Gauthier and Aline Renaud. In 1865, Gauthier married Philomène Daunais. He served as mayor of Saint-Lin from 1872 to 1880.[2] He ran unsuccessfully for a seat in the House of Commons in 1882. He was first elected in 1887; that election was appealed but he won the by-election which followed in 1888. His election in 1891 was declared void in 1892 and Hormidas Jeannotte was elected by acclamation in the by-election that followed. Gauthier defeated Jeannotte in the 1896 federal election. He died in Saint-Lin at the age of 69.[2]
