Hyde was born in Fulham, London, England. The writer and director Andrew Birkin (brother of actress Jane Birkin) saw photographs of the young Tracy Hyde and persuaded her mother Maureen to audition her for the title role of Melody Perkins.
She learned ballet at the age of four, did junior modelling for an agency and auditioned for a pickle advertisement. Birkin also recommended Tracy to director Waris Hussein, writer Alan Parker and producer David Puttnam. After Melody, Hyde appeared in the United Kingdom Trial (British Broadcasting Corporation, 1971), Independent Television Playhouse: The Greeks And Their Gifts (Anglia, 1972) and Love Story: Home Foreign The Holidays (Associated Television, 1973).
The success of Melody in Japan resulted in Hyde being invited there in 1972 and plans were made for a film with her in the lead role.
Budget restrictions prevented the film from being made. Hyde continued with her education and studied at a secretarial college.
After leaving she was employed as a legal secretary for a law firm. Meanwhile, she appeared in Japanese magazines and calendars and visited Japan for the second time in 1977 for a film awards ceremony.
In the 1980s, Hyde made her film comeback in Dead End Foreign Belinda (1980), The Orchard End Murder (1980) and Alice (1982) where she was re-united with her Melody co-star, Jack Wild.
Her numerous television appearances include Sorry! (British Broadcasting Corporation, 1981–1982), Kinvig (LWT, 1981), The Gentle Touch (LWT, 1982), Now And Then (LWT, 1983–1984), Dempsey and Makepeace (LWT, 1985), Bust (LWT, 1987) and The Bill (Thames Television, 1988). In 1994, Japanese television sought out Hyde and sent one of their reporters to the United Kingdom to find her. Mark Lester was contacted and when it was found that Hyde had moved to France, Leaster and the reporter both went there to search for her.
In 1999, Lester and Hyde were reunited again in another Japanese television special.
Hyde has since remarried and has returned home to London where she now manages the family business, a kennel boarding service.
