Bridget St John (born Bridget Anne Hobbs; 4 October 1946 in East Molesey, Surrey, England) is an English singer-songwriter and guitarist, best known for the three albums she recorded between 1969 and 1972 for John Peel's Dandelion record label. Peel produced her debut album, Ask Me No Questions. She also recorded a large number of BBC Radio and Peel sessions and toured regularly on the British college and festival circuit.

St John appeared at leading folk venues in the UK, along with other folk and pop luminaries of the time such as Nick Drake, Paul Simon, and David Bowie, among others. In 1974 she was voted fifth most popular female singer in that year's Melody Maker readers poll. Blessed with a "rich cello-like" vocal style, she is also an accomplished guitar player who credits John Martyn and Michael Chapman as her "musical brothers".
