St Peter's is an area of Broadstairs, a town on the Isle of Thanet in Kent. Historically a village, it was outgrown by the long-dominant settlement of the two, Broadstairs, after 1841. Originally the borough or manor of the church of St. Peter-in-Thanet, it was said to be the largest parish east of London, at least until Broadstairs became a separate parish on 27 September 1850. The two settlements were formally merged administratively in 1895.
