The Church of St Mary Magdalene is the Church of England parish church for the village of Ditcheat, Somerset, England. There has been a church on the site since 824, and the present building owes much of its grandeur to the Abbots of Glastonbury. Historic England have designated it a Grade I listed building.

The first church at Ditcheat is believed to have been founded in 824, though all traces of this building have disappeared with centuries of rebuilding. This date comes from an ancient parish book, found by Rev. Henry Tripp in an old chest during the early 1930s.

In 842, Æthelwulf, King of Wessex, granted an estate of 25 hides of land in Ditcheat to Eanulf, a Somerset ealdorman, which included the villages of Ditcheat and Lottisham. In 867, Eanulf, dying, gave the estate to the Abbot of Glastonbury. Glastonbury Abbey continued to manage the estate until the abbey was dissolved in 1539, as part of the Dissolution of the Monasteries.

In the 12th century, the church was demolished and rebuilt, and as such, no trace of the Saxon church remains. The Norman church that replaced it was likely cruciform in plan, as was common with many churches built at that time. The present church also incorporates 12th-century work in the tower and transepts, which gives further evidence that the Norman church likely comprised a simple nave, tower, transepts and chancel.

In the 13th century, during the reign of Henry III, the dedication of the church was altered to its present form of St Mary Magdalene. The previous dedication of the church is unknown. The 13th century also saw the rebuilding of the chancel, at the time only one storey high, in the Early English Gothic style.

In the 14th century, the chancel was raised by a further stage, unusually by adding a row of windows directly on top of the old, giving the appearance of a two-storey building.

During the final decades of the 15th centuries, the church saw major rebuilding, which included demolishing the old Norman transepts and nave, and rebuilding them in the Gothic style. The tower, primarily dating from the 12th century, was also heightened by adding an additional storey, and massive corner buttresses added to the eastern corners to support the added weight. A fan vault was added to the empty space inside the tower; it was most likely a lantern tower before this. A rood loft was added across the nave arch, separating the nave from the tower and east end.

The church saw much change again during the 16th and 17th centuries, including the removal of the rood loft and staircase, and damage caused by the English Civil War. The church, like many others, was damaged by Oliver Cromwell and his forces, including smashing many stained glass windows, destroying monuments and furnishings, and decapitating the head from the churchyard cross. As such, many of the windows in the church, especially in the nave, are now made from clear glass.
