St John the Baptist's Church, Brighton

St John the Baptist's Church is a Roman Catholic church in the Kemptown area of the English city of Brighton and Hove. It was the first Roman Catholic church built in Brighton after the process of Catholic Emancipation in the early 19th century removed restrictions on Catholic worship. Located on Bristol Road, a main road east of the city centre, it is one of 11 Catholic churches in Brighton and Hove.

The first Catholic place of worship in Brighton was established above a shop in 1798; it was one of the earliest in Britain. In 1805 the priest in charge, a French émigré, started to raise money for a permanent building; a site on High Street, east of the Royal Pavilion and Old Steine, was found, and the Classical-style church was completed in 1807. It was demolished in 1981. St John the Baptist Catholic School moved away from its original site next to the church in 1989, when a new building was provided on Whitehawk Hill. The convent chapel is now used as a rest home, although its origins as a chapel are still apparent. The church holds Masses on Saturday evenings, Sunday mornings and Holy Days of Obligation.
