St Katharine Cree is a Church of England church on the north side of Leadenhall Street near Leadenhall Market.
The parish served by the church existed by 1108, when it was served by the Augustinian Holy Trinity Priory, Aldgate, also called Christ Church, which was founded by Maud, queen at the time of King Henry I. The parishioners used the priory church but this proved unsatisfactory and disruptive to the priory’s activities.
The prior partly resolved the problem in 1280 by founding St Katharine Cree as a separate church for the parishioners. The site of the present church was originally in the priory’s churchyard and it is possible that the church began as a cemetery chapel. It took its name from the priory, "Cree" being a corrupted abbreviation of "Christ Church". It was initially served by a canon appointed by the prior but this did not prove satisfactory either, so in 1414 the church was established as a parish church in its own right. The present tower was added about 1504.
The present church was built in 1628–30, retaining the Tudor tower of its predecessor. It is larger than the previous church, incorporating a piece of ground previously occupied by a cloister on the north side, and the floor level is considerably higher. The rebuilt church was consecrated by William Laud, Bishop of London on 31 January 1631. His vestments and the form of service that he used for the consecration were later held against him in his trial and conviction for heresy, when Puritans accused him of having displayed Catholic sympathies through his "bowings and cringings." He is commemorated by a chapel in the church.
The church escaped the Great Fire of London in 1666 and suffered only minor damage in the London Blitz of the Second World War. However, structural problems required extensive restoration in 1962. It is now one of the City’s Guild churches.
