Miro was born into a Jewish working-class family in London. Her father ran a Covent Garden grocery stall. Her parents were keen on culture and saved, so the family could take holidays in Italy to see the art there. She went to school at Copthall grammar school in North London, then studied painting at the Slade School of Fine Art, which she says helped her understand art from the point of view of the artist. For a short period during the early 1970s she worked as a secondary schoolart teacher. She married businessman Warren Miro and had a son and daughter in the 1970s. She says she lost the creative urge during this period because she was "immersed in family". In 1985, when her children were old enough, she started her first gallery in Cork Street, London, taking over the galleryspace previously owned by dealer Robert Fraser. In the late 1980s, she opened a second gallery in Florence in Italy, but shut it in 1991 after the art market slump. In 2000 her London gallery moved to a much larger 8,000 square foot premises in East London. Two of her baby-sitters at that time were a couple who later became well-known artists, Jake Chapman, who showed at her gallery, and Sam Taylor-Wood. One of her sources for finding new artists was the Royal College of Art. Through tutor Peter Doig she learnt about Chris Ofili, Cecily Brown and Chantal Joffe. She discovered Thomas Demand at another London college, Goldsmiths. She has a reputation for integrity amongst clients; one of them, Arthur Goldberg, said, "She's a real quality person. That goes somewhere in the art world, where not every dealer can be trusted." She is widely known within the art world but less so outside it and has been described as "the quiet woman of British art". In 2001, despite her success, she rejected identification with the art establishment, saying "I like to think I still take risks in the gallery with younger artists. To me, 'establishment' just means dull." In October 2013 Miro launched her second art gallery in London, known as Victoria Miro Mayfair. In May 2017 she opened a third gallery Victoria Miro Venice.
