Lyme Regis Cemetery is the principal cemetery in the English town of Lyme Regis, Dorset. Estimates for the number of burials in the cemetery range from 3,570 to over 5,000, nearly half of which may today be unmarked. It was opened on 16 November 1856 as a replacement for the graveyard surrounding St Michael the Archangel – Lyme Regis' parish church – which had long suffered from erosion due to its close proximity to the sea.
