St Mary's Church is a parish church in the Church of England in East Leake, Nottinghamshire.

The church is Grade I listed by the Department for Digital, Culture, Media and Sport as a building of outstanding architectural or historic interest.

The church dates from the Norman period but has substantial later medieval work. Until the fourteenth century, the church was dedicated to St Leonard, but the church was re-dedicated to St Mary who was more popular.

After the chancel collapsed in the nineteenth century, a major restoration was carried out in 1886 by W. S. Weatherley.

There are stained glass windows by Charles Eamer Kempe, James Powell and Sons and Heaton, Butler and Bayne.

The church has a pipe organ by Ingram built in 1914. The specification of the organ can be found on the National Pipe Organ Register.

In April 2021 a new organist, Richard Babington, was appointed.

The church has six bells.

The church runs regular Life Explored courses for anyone interested in exploring Christianity.
