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.

Michael Llewelyn Davies was – along with his four brothers – the inspiration for J. M. Barrie's characters Peter Pan, the Darling brothers, and the Lost Boys. Late in life, his only surviving brother Nico described him as "the cleverest of us, the most original, the potential genius." He died in ambiguous circumstances, drowning with a close friend – and possible lover – just short of his 21st birthday. He was a first cousin of English writer Daphne du Maurier.
