St Mary's Church is in the village of Allithwaite, Cumbria, England.

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

[3] These were financed by Miss Mary Winfield Lambert of Boarbank Hall, who died in 1857 and bequeathed £2,500 (equivalent to £300,000 in 2023)[4] towards the church, £1,000 for the school, and £1,500 for the vicarage.

[5] St Mary's is constructed in rock-faced limestone; it has sandstone ashlar dressings, and slate roofs.

The stained glass in the east window in the aisle dates from 1950 and is by Abbot and Company.
