Sandford Lock is a lock on the River Thames in England, situated at Sandford-on-Thames which is just south of Oxford. The first pound lock was built in 1631 by the Oxford-Burcot Commission although this has since been rebuilt. The lock has the deepest fall of all locks on the Thames at 8 ft 9in (2.69m) and is connected to a large island which is one of three at this point. The lock lies at the end of Church Lane in Sandford on Thames.

Upstream from the lock, the main weir connects the second island to the opposite bank on the Kennington, Oxfordshire side. This is the location of the infamous Sandford Lasher, a treacherous weirpool where many have drowned. Another weir links the two lower islands.
