Alison MacCallum (born 7 April 1951), also written Alison McCallum, is an Australian rock singer from the late 1960s and 1970s. Her two studio albums are Fresh Water (March 1972) and Excuse Me (October 1975). In March 1972 she issued her most successful charting single, "Superman", which peaked at No. 12 on Go-Set's National Top 40. In August that year MacCallum provided lead vocals for the Labor Party's campaign theme song, "It's Time", for the 1972 election. By the late 1970s, she had concentrated on session work and then "disappeared from public view". According to Australian musicologist, Ian McFarlane, MacCallum was "a soul/blues stylist of considerable flair and passion".
