Holy Trinity Church, in Marylebone, Westminster, London, is a Grade I listed former Anglican church, built in 1828 by Sir John Soane. In 1818 Parliament passed an act setting aside one million pounds to celebrate the defeat of Napoleon. This is one of the so-called "Waterloo churches" that were built with the money. It has an external pulpit facing onto Marylebone Road, and an entrance with four large Ionic columns. There is a lantern steeple, similar to St Pancras New Church, which is also on Euston Road to the east.

By the 1930s, it had fallen into disuse and in 1936 was used by the newly founded Penguin Books company to store books. A children's slide was used to deliver books from the street into the large crypt. In 1937 Penguin moved out to Harmondsworth, and the Society for Promoting Christian Knowledge (SPCK), an Anglican missionary organisation, moved in. It was their headquarters until 2006, when they relocated to Tufton Street, Westminster (they have since moved again to Pimlico). The church is currently the location of the world's first wedding department store, The Wedding Gallery, which is based on the ground floor and basement level. The first floor is used as an events space operated by One Events and known as "One Marylebone".

The former church stands on a traffic island by itself, bounded by Marylebone Road at the front, and Albany Street and Osnaburgh Street on either side; the street at the rear north side is Osnaburgh Terrace.
