Shirley Dorismond is a Canadian politician and former union leader and nurse, who represents the electoral district of Marie-Victorin in the National Assembly of Quebec. She is a member of the Coalition Avenir Québec (CAQ), winning a 2022 by-election following the resignation of the former MNA Catherine Fournier. She is the first CAQ MNA for Marie-Victorin, as the district had been a Parti Québécois (PQ) stronghold since its creation in 1980, with only a one-year gap in 1984 when the Liberal party won a byelection, until Fournier left the PQ in 2019.
