St Mary Moorfields is a Roman Catholic church in Eldon Street near Moorgate, on a site previously known as Moorfields. It is the only Catholic church in the City of London. Prior to a 1994 boundary change, the church was in the Borough of Hackney, such that there were no Catholic churches in the City.

The present building, located at 4–5 Eldon Street, was opened in 1903, after the previous building had been demolished in 1899. However, the foundation had a long history prior to this. A chapel was opened in 1686, but was suspended in 1689, in the aftermath of the Revolution of 1688.

The church serves as a hub for evangelism, especially directed at young people who work in the surrounding financial district. The church hosts monthly Opus Dei meetings, and is also affiliated with the St Francis of Assisi Ramblers.
