Enid Stacy (10 June 1868 – 4 September 1903) was an English socialist activist. Stacy was born on 10 June 1868 in Westbury, Gloucestershire, the eldest of the Irish painter Henry Stacy and his wife Rose Deeley's four children. The family moved to Bristol in 1881. She was raised in a Christian socialist household; her brother helped found the Bristol and Clifton Christian Socialist Society and her father later became involved with the Bristol Socialist Society. She studied at the University of Bristol, where she won the Whitworth Scholarship, and she then became a tutor at the Redland High School for Girls. There, she met Katharine St John Conway, with whom she shared an interest in John Ruskin and Anglo-Catholicism.
