Holy Trinity Gough Square [1] was a Victorian church in the City of London.

[2] The church was built on a small, triangular site, at the junction of Great New Street and Pemberton Row, given by the Goldsmiths Company.

[2] The main body of the church was hexagonal, with a large octagonal recess on the eastern side serving as a chancel.

[2] The social reformer Charles Booth noted it served the area's poorer citizens.

[3] As the century wore on legislation was passed to reduce the number of City churches and after a comparatively short existence[4] the then Bishop of London authorised the reunification of the two parishes,[5] the proceeds from the sale going towards the building of St Mellitus, Hanwell.
