John Jenkins (known also as Ifor Ceri) (8 April 1770 – 20 November 1829) was a Welsh priest in the Church of England and an antiquarian.
He played a leading role in the establishment of eisteddfodau in Wales in the nineteenth century.
He was ordained in 1793 and his first post was at Whippingham, Isle of Wight, where he acted as curate to the rector, who was his uncle.
After illness, he returned to Wales to become rector of Manordeifi in Pembrokeshire, before Thomas Burgess (the Bishop of St David's) appointed him as vicar of Ceri in Montgomeryshire in 1807.
