All Saints' Church is a Grade I listed parish church in the Church of England serving the parish of Markham Clinton in West Markham, Nottinghamshire.
The church was built in the 12th century. It was repaired in 1872 and restored between 1930 and 1945. It is in a parish with two other churches:
Somewhat confusingly, Milton Mausoleum is sometimes also referred to as All Saints' Church, West Markham.
The church contains an Organ dating from 1860 by Bevington and Sons.
The church has one bell which is hung on half a wheel and is swing chimed.
The church is the burial place of Henry Pelham-Clinton, 4th Duke of Newcastle. After his wife died in 1822, the 4th Duke built a church and mausoleum at Milton, Nottinghamshire, which was completed in 1833, and replaced All Saints as the parish church. In 1949 All Saints became the parish church again after restoration; the Mausoleum was left to decay until 1972 when it was taken into guardianship by the Churches Conservation Trust.
West Markham church is part of the Tuxford Benefice.
