Day's Lock is a lock on the River Thames near Dorchester-on-Thames, Oxfordshire, England on the Dorchester side of the river.

The pound lock was built in 1789 by the Thames Navigation Commissioner. The lock is across the river from the small village of Little Wittenham and is overlooked from the south by the hills of Wittenham Clumps, with a particularly good view from Round Hill.

The weir runs straight across the river from the other side of the lock island.

Day's Lock is the main gauging station for the measurement of the water flow in the River Thames.

The Thames Path crosses the river here.

The World Poohsticks Championships, on behalf of the RNLI, have taken place annually here since 1983.
