Irénée Vautrin was a Canadian politician from Quebec.
Vautrin ran as a Liberal candidate for the Legislative Assembly of Quebec in the 1919 election for the district of Montréal–Saint-Jacques and won but was defeated by the Conservative candidate Joseph-Ambroise-Eusèbe Beaudoin in the 1923 election.
Vautrin was appointed to the Cabinet and served as Deputy House Speaker from 1930 to 1934, Minister without Portfolio in 1934 and Minister of Colonization from 1934 until his defeat in the 1935 election by the Conservative candidate Henry Lemaître Auger.
Soon after he left office, Vautrin appeared before the Standing Committee on Public Accounts and became one of the favourite targets of Conservative Leader Maurice Duplessis, who exposed the corrupt practices of the Liberal government.
The undesired attention earned Vautrin, who had bought pants by the colonization fund, the unflattering nickname Les culottes à Vautrin.
