Christ Church, Marylebone, also called Christ Church, Lisson Grove, and Christ Church, Cosway Street, is a Grade II* listed former Church of England church, built in the 1820s in Marylebone in the City of Westminster to designs by Thomas and Philip Hardwick.

Philip Hardwick was an English architect, particularly associated with railway stations and warehouses in London and elsewhere. Hardwick is probably best known for London's demolished Euston Arch and its twin station, the original Birmingham Curzon Street, which stands today as the oldest railway terminus building in the world.
