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.

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.

[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.
