Huguette Plamondon (January 6, 1926 - September 29, 2010) was a trade unionist in Quebec, Canada. A trailblazer and leader in the Quebec, Canadian and international labour movements, she dedicated the bulk of her efforts to representing the United Packinghouse Workers of America and then the United Food and Commercial Workers, after the UPWA merged with the Amalgamated Meat Cutters in 1979 to create the UFCW. She also served as a vice-president of the Canadian Labour Congress from 1956 until 1988.
