Bridget St John (born Bridget Hobbs, 4 October 1946, South London) is a British singer and songwriter, 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. Her first stage performances were proposed and staged by Bernard Brandon, her drama mentor at Sheffield University in 1964-5. After a few cameo performances in between zany sketches by the Revue team her very first "proper gig" was at a pub in Rotherham. That was the night she walked back home to Sheffield under the stars and knew she was poised to become one herself. In 1974 she was voted fifth most popular female singer in that year's Melody Maker readers poll.

An accomplished guitar player, she credits John Martyn and Michael Chapman as her "musical brothers".
