All Souls Church is a conservative evangelical Anglican church in central London, situated in Langham Place in Marylebone, at the north end of Regent Street. It was designed in Regency style by John Nash and consecrated in 1824.

Langham Place is a short street in Westminster, central London, England. Just north of Oxford Circus, it connects Portland Place to the north with Regent Street to the south in London's West End. It is, or was, the location of many significant public buildings, and gives its name to the Langham Place group, a circle of early women's rights activists.
