St Peter's Church is in the village of Finsthwaite, Cumbria, England.

It is an active Anglican parish church in the deanery of Windermere, the archdeaconry of Westmorland and Furness, and the diocese of Carlisle.

[2] St Peter's was designed by the Lancaster partnership of Paley and Austin.

They were the winners of a competition to design "mountain chapels" organised by the Carlisle Church Extension Society in 1873.

[2] The ceiling is painted with scrollwork, and with angels carrying copies of the Beatitudes.

Around the nave and window arches are a stencilled frieze, part of which has been covered with whitewash.

These include the altar rails, the chancel floor, the pulpit, the lectern, and the font, which is made from fossiliferous marble.
