Michelle A. MacPherson (born May 11, 1966), also known by her married name Michelle Hojnacki, is a former backstroke and butterfly swimmer from Canada. After being selected for the Canadian Olympic swim team for the 1980 Summer Olympics in Moscow, MacPherson was unable to participate because of the United States-led boycott of the Moscow Olympics. Four years later, she represented Canada at the 1984 Summer Olympics in Los Angeles, California. There McPherson won a bronze medal in the women's 4×100-metre medley relay, alongside Canadian teammates Anne Ottenbrite, Reema Abdo and Pamela Rai.
