Mumbles (Welsh: Mwmbwls) is a headland sited on the western edge of Swansea Bay on the southern coast of Wales. The name Mumbles is also applied to the district encompassing the electoral wards of Oystermouth, Newton, West Cross, and Mayals. In the 2018 Best Places to Live in the UK report, The Sunday Times listed Mumbles as the best in Wales.
Mumbles has been noted for its unusual place name. The headland is thought by some to have been named by French sailors, after the shape of the two anthropomorphic islands which comprise the headland: the word "Mumbles" may be a corruption of the French les mamelles, meaning "the breasts." Another possible source of the name is from the word Mamucium which is generally thought to represent a Latinisation of an original Brythonic name, either from mamm- ("breast," in reference to a "breast-like hill") or from mamma ("mother," in reference to a local river goddess).
A lifeboat station has operated from Mumbles since 1866. In 1947, the entire lifeboat crew was lost at sea, attempting to rescue the crew of the SS Samtampa, in what has become known as the Mumbles lifeboat disaster. The nearest church, All Saints' Church, Oystermouth, contains memorials to the crew.
