"Mirror Mirror" (also titled as "Mirror Mirror (Mon Amour)") is a 1981 single by British pop duo Dollar from their third album, The Dollar Album. The song was co-written by Trevor Horn and Bruce Woolley, and produced by Horn.

The song was the follow-up single to "Hand Held in Black and White", which had revived the duo's career in the Summer of 1981 when it became their first top 20 hit for a year and a half. "Mirror Mirror" charted over the Christmas period in 1981 and was the biggest hit of Dollar's career. It reached #4 in the UK and spent a total of 17 weeks in the chart. It also reached #5 in Ireland.

A promotional video was made to accompany the song, featuring members David Van Day and Thereza Bazar as wooden dolls coming to life. The B-side of the single was a song written by the duo called "Radio", which had been the opening track on their second album The Paris Collection (1980).
