The Church of the Holy Trinity is a Grade II* listed church, incorporating Saxon and medieval elements, located in the town of Wolverton, Buckinghamshire, England.^[1] The modern church was rebuilt between 1809 and 1815.

The Church of the Holy Trinity is the original parish church of the Saxon settlement of Wolverton^{[citation needed]} and overlooks the valley of the Ouse river, near the site of the Norman motte-and-bailey castle.^[2]

In the early 19th century the old medieval building was replaced by a new church, begun in 1809 and completed in 1815.^[2] The new church incorporates the 14th-century central tower of the old church, but this was re-cased in new masonry.^[3][2]

The new stonework used Warwickshire sandstone, brought in from Attleborough, and was brought to the site by barge on the recently opened Grand Junction Canal.^[3]

Next door to the church is a house built in 1729, which later became the vicarage; the front door has stonework from the nearby, demolished manor house of the 16th century, including the de Longueville family coat of arms, and pieces from the earlier church building.^[4]

The church was Grade II* listed on 12 June 1953.^[1]

The rector is The Revd Gill Barrow-Jones.^[5]

Among those buried in the churchyard are the stonemason George Wills, grandfather of the chemist George S. V. Wills.
