St George's, Hanover Square, is an Anglican church, the parish church of Mayfairin the City of Westminster, central London, built in the early eighteenth century as part of a project to build fifty new churches around London (the Queen Anne Churches). The church was designed by John James; its site was donated by General William Steuart, who laid the first stone in 1721. The building is one small block south of Hanover Square, near Oxford Circus. Because of its location, it has frequently been the venue for society weddings.
