Holy Trinity Church is the Anglican parish church of Rudgwick, a village in the Horsham district of West Sussex, England.

The oldest part of the church is the font, which is made from Horsham or Sussex Marble and dates from the 12th century.

Parts of the south wall may have been retained from the original church and so may be as old as the tower.

Holy Trinity dates from the 13th century, when about the year 1260 Alard the Fleming who owned the great manor of Pulborough and was granted the right to hold a fair at Rudgwick on “the eve, feast and morrow of the Holy Trinity” (Trinity Sunday).

Holy Trinity Church was designated a Grade I Listed building on 22 September 1959.
