The Bishop of Willesden is an episcopal title used by a suffragan bishop of the Church of England Diocese of London, in the Province of Canterbury, England.^[1] The title takes its name after Willesden, an area of the London Borough of Brent; the See was erected under the Suffragans Nomination Act 1888 by Order in Council dated 8 August 1911.^[2]

The post was created in 1911, and was the third suffragan bishopric erected in the diocese since 1879. The new bishop was given oversight of four rural deaneries: Hampstead, Hornsey, St Pancras and Willesden, previously the responsibility of the Bishop of Islington.^[3][4] By November 1911, the Bishop's residence was 13 Cannon Place, Hampstead.^[5]

In the experimental area scheme of 1970, the bishop was given oversight of the deaneries of Brent, Harrow, Ealing East and West, and Hillingdon.^[6] The bishops suffragan of Willesden have been area bishops since the London area scheme was founded in 1979.^[7] The bishop now has responsibility for the Willesden Episcopal Area, that is, the Archdeaconry of Northolt, comprising four deaneries: Brent, Ealing, Harrow and Hillingdon.^[8]
