Itchingfield is a parish in the north east corner of the county of West Sussex. There is now only a small hamlet called Itchingfield in which the church of St Nicolas is situated. The main centre of population is Barns Green, a village in the south of the parish.
Today Itchingfield Parish has a population of about 1500, most of them living in Barns Green. The parish is almost wholly agricultural, although only a small number of parish residents now work in agriculture. The largest employer in the parish is Muntham House School, a Charitable Trust providing educational facilities for boys.
