Pen-clawdd is a village on the Gower Peninsula in South Wales. The village sits on the southern banks of the Loughour estuary, some 4 miles, 7km, north west of Llanrhidian, 2.5 miles, 4km, west of Gowerton, and 8 miles, 12km, west of Swansea.

The village is famous for its cockle industry and at one time 1,000 tons of cockles were being collected and sold.

Pen-clawdd cockles are collected from the Burry Estuary and the cockles are sold worldwide. Up until 1970s the cockles were gathered by women using hand-rakes and riddles with the help of donkey carts. Today they are harvested mostly by men, still by hand but with the donkeys replaced by tractors. The Pen-clawdd market also sells a number of other Welsh food delicacies including laverbread (laver seaweed washed and boiled) and salt marsh lamb (lambs bred on the salt marshes of the Loughor estuary).

As with many south Wales towns and villages Rugby is one of the town's greatest passions. Penclawdd RFC are a successful rugby union club, recently having celebrated 125 years of rugby playing. In 2005 the club won the Division 3 West League tournament.
