Lady Lyttleton was a barque that sunk in the Emu Point Channel in Oyster Harbour near Albany in the Great Southern region of Western Australia.

[2] In 1866 the vessel was sold to Harold Selwyn Smith in Melbourne and registered at the port there.

The crew had already jettisoned part of the cargo with the rest being unloaded in Albany before it sailed to Emu Point for repairs.

Lady Lyttleton was hove down to the shore by tackles from the masthead but the ship slipped and then foundered and sank on 17 July 1867.

[3] The Western Australian Museum surveyed and partially excavated the site in 1978 and in 1990 with several artefacts being retrieved.
