St Giles in the Fields is the Anglican parish church of the St Giles district of London. The parish stands within the London Borough of Camden and forms part of the Diocese of London. The church, named for St Giles the Hermit, began as the chapel of a 12th-century monastery and leper hospital in the fields between Westminster and the City of London and now gives its name to the surrounding urban district of St Giles in the West End of London, situated between Seven Dials, Bloomsbury, Holborn and Soho. The present church is the third on the site since 1101 and was rebuilt most recently in 1731–1733 in Palladian style to designs by the architect Henry Flitcroft.

St Giles is an area in London, England and is located in the London Borough of Camden. It is in Central London and part of the West End. It gets its name from the parish church of St Giles in the Fields. The combined parishes of St Giles in the Fields and St George Bloomsbury were administered jointly for many centuries; leading to the conflation of the two, with much or all of St Giles usually taken to be a part of Bloomsbury. Points of interest include the church of St Giles in the Fields, Seven Dials, the Phoenix Garden, and St Giles Circus.
