King's Quoit is a Neolithic burial chamber in Manorbier, 5 miles (8.0 km) east of Pembroke, Pembrokeshire, Wales. It is a scheduled monument.

The cromlech known as the King's Quoit is south of Manorbier bay and beach. The monument is on high land above the steep cliff overlooking the bay. The capstone, 4 metres (13 ft) by 2.5 metres (8 ft 2 in), and 0.5 metres (1 ft 8 in) thick, is supported partly by the rising ground, partly by two upright stones; another upright to the east has fallen away. The chamber is partly below ground.
