St Martin's Church stands in the centre of the town of Bowness-on-Windermere, 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.

This was originally a chapel of ease to the mother church at Kendal, becoming a parish in its own right in 1348 at which time the churchyard was consecrated.

The church at this time had a simple plan, consisting of a nave with aisles, and a west tower.

[6] Paley and Austin extended the chancel, raised the tower, to which they added a saddleback roof, and replaced the seating.

Around this time murals were painted on the walls by Henry Hughes of London, who also restored the east window.

It was made into a memorial chapel in 1922 by Dolman to commemorate the 71 men from the parish who died in the First World War and as a thanksgiving for those who returned.

[5][6] Later in the 20th century, pews were removed from the back of the church to make a social area, and the choir vestry was made into a children's wing.

[2][5][6] Hyde and Pevsner, in the Buildings of England series, describe the interior of the church as being "a strange sight", because it is constructed entirely in thickly plastered, white-painted, rubble.

The reredos dates from 1870, is made from marble, and contains mosaics that depict the symbols of the Four Evangelists and the Passion;[5] it is by Bell and Almond.

[7] In front of the lectern is a display case made by Arthur Simpson in 1907 in memory of the artist Dan Gibson.

One of the older features of the window, at the top, is the coat of arms of George Washington, whose ancestor, John Wessington, owned land at nearby Warton.

In the churchyard is a tomb with a headstone dated 1822 inscribed to the memory of a freed slave named Rasselas Belfield, who is described as "A Native of Abyssinia".

[10] Against the wall of the south aisle is a white veined marble slab to John Bolton, a slave trader and plantation owner who died in 1837.
