Ipswich Minster, previously known as St Mary-le-Tower, is the civic church of Ipswich, Suffolk, England and a Grade II* listed building. It was in the churchyard of St Mary that the town charter of Ipswich was written in 1200.
Although medieval, the church mostly dates from 1860 to 1870, when it was rebuilt by Richard Phipson. Rebuilding was funded by George Bacon, banker and philanthropist. The church, then known as St Mary-le-Tower, is mentioned in the Domesday Book, demonstrating that the site has been occupied by a church since at least 1086.
On 19 January 2025, the church known as St Mary-le-Tower, was redesignated as Ipswich Minster in recognition of its increasingly important role in serving the community of Ipswich.
The church contains a memorial brass, on a chancel pier, to H.A. Douglas-Hamilton, vicar from 1915 to 1925. There are also four brasses in the chancel floor.
The church has a large three-manual pipe organ, which has its origins in an instrument by Renatus Harris of 1690. There was subsequent work by Henry Willis, Spurden Rutt and Bishop & Son. A specification of the organ can be found on the National Pipe Organ Register.
Originally there were five bells and a Sanctus in 1553 of which Miles Graye I of Colchester recast the Treble in 1607 and the Tenor in 1610. The church was the first in Suffolk to achieve a tower a peal of 12 bells in 1865. With the addition of a sharp second in 1980, the current bells are all by John Taylor & Co, of Loughborough (except for No. 7, which is by Mears & Stainbank of London).
