Jean Paul Lemieux, CC GOQ (18 November 1904 – 7 December 1990) was one of the foremost painters of twentieth century Quebec.
He was born in Quebec City, where he also died (Colin S. Macdonald claims he died in Montreal). He was raised in Quebec City until 1916, when his family moved to Berkeley, California. In 1917, the family returned to Quebec and settled in Montreal. In 1960, works by Lemieux along with those of Edmund Alleyn, Graham Coughtry, Frances Loring and Albert Dumouchel represented Canada at the Venice Biennale.
Jean Paul Lemieux received several awards for his works, including the Louis-Philippe Hébert prize in 1971 and the Molson Prize for the Canada Council for the Arts in 1974. In 1968, he became a Companion of the Order of Canada. He was also a member of the Royal Canadian Academy. In 1997, he was posthumously made a Grand Officer of the National Order of Quebec.
