Nicholas Litlyngton, also spelled Litlington or Littlington (died 29 November 1386), was successively prior and abbot of Westminster Abbey.
He continued the programme of his predecessor, Simon Langham, to restore the monastery to its former glory following the Black Death.
In 1373–1374, Nicholas represented Edward Despenser in England while he was taking part in the Great Chevauchée in France.
In October 1378, he attended in Gloucester to defend his actions in admitting an alleged traitor, Robert Hawley, into the abbey, where he was murdered.
He died at his house in La Neyte on 29 November and was buried with his armour in the chapel of Saint Blaise on 17 December.
