Capel Salem is a Grade II listed building in the hamlet of Pentre Gwynfryn, near Llanbedr, Gwynedd, Wales. This Baptist chapel building is about a mile upriver of Llanbedr, on a ridge between the two valleys, 300 yards (270 m) upstream from where the two rivers meet. The building was begun in 1826 and completed in 1851, but ten years later it was extended to include the chapel house and to remodel the interior.
