Trusthorpe is a small coastal village in the civil parish of Mablethorpe and Sutton, in the East Lindsey district of Lincolnshire, England.

It is built of red brick with ashlar dressings, and the three stage tower has stepped corner buttresses.

At the east end of the nave is a wall monument to William Loft who died in 1854.

Mr Charles Foster bought it and moved it to Trusthorpe where it was incorporated into a new mill.

[5] When Bolingbroke Castle was repaired for use of auditors of the Duchy of Lancaster working for Edward VI, lead for the roof of the gatehouse was brought from a chapel at Trusthorpe.
