Piers Calveley Claughton (8 June 1814 – 11 August 1884) was a Bishop in the Anglican church.
He was born the son of Thomas Claughton (M.P. for Newton, Lancashire, 1818-25) at Haydock Lodge, Winwick, Lancashire and was educated at Brasenose College, Oxford, where he graduated B. A. in 1835, and M.A. in 1838.
After ordination in 1838 he was made rector of Elton, Huntingdonshire from 1842 to 1843 and again from 1845 to 1859, before becoming the first Bishop of St Helena (1859–1861) and a subsequent translation to the see of Colombo (1862–1871).
