King's Lock

King's Lock is a lock on the River Thames in England. It is in open country about 1 km north of Godstow, to the north of Oxford, Oxfordshire, at grid reference SP478102, on the southern bank of the river. The lock was one of the last pound locks built on the Thames, built by the Thames Conservancy in 1928 to replace the former flash lock. It has the smallest fall of any lock on the river, 0.77 m (2 ft 6 in).

The lock is on the southern side of a large island. On the opposite side of the river is the start of the Wolvercote Mill Stream leading to Duke's Cut, which connects the Thames to the Oxford Canal. The Mill Stream rejoins the Thames below Godstow Lock. King's Weir is on the other side of the island below Duke's Cut. There is a small visitor information centre at the lock.
