The Church of the Holy and Undivided Trinity with Saint Jude, Upper Chelsea, commonly called Holy Trinity Sloane Street or Holy Trinity Sloane Square, is a Church of England parish church in London, England. It was built in 1888–90 at the south-eastern side of Sloane Street, to a striking Arts and Crafts design, by the architect John Dando Sedding, and paid for by 5th Earl Cadogan, in whose London estate it lay. It replaced an earlier building only half its size which, at the time of its demolition, was less than 60 years old.
