Marie-Josée Simard (born November 29, 1956) is a Canadian percussionist and music educator living in Quebec.

She was born in La Baie (now part of Saguenay). She performed on the vibraphone with her parents' orchestra. Simard was taught by her mother until she entered the Conservatoire de musique et d'art dramatique du Québec in 1974. Then, from 1976 to 1979, she studied at the Conservatoire de musique du Québec à Montréal (CMM). She was the first woman to graduate as a percussionist and the first woman to win a first prize in percussion from the CMM.

In 1992, she represented Canada in a Metropolitan Opera benefit concert. She was a soloist with Canadian orchestras including the Montreal Symphony Orchestra, the Orchestre des jeunes du Québec, the Kingston Symphony, the Edmonton Symphony Orchestra, the Vancouver Symphony Orchestra and the Kitchener-Waterloo Symphony.
