Horndon-on-the-Hill is a village and Church of England parish in the unitary authority of Thurrock, in the county of Essex, England. It is located close to the A13, around one mile northwest of Stanford-le-Hope and around two miles northeast of Orsett. The village area falls within the Orsett ward of Thurrock District Council.
Horndon-on-the-Hill has one church, the Church of St Peter and St Paul, which dates from the 13th century and is Grade I listed. It also has a primary school, a recreational park and two public houses, The Swan and The Bell.
Horndon-on-the-Hill appears in the Domesday Book of 1086 as Horninduna, meaning "horn-shaped hill". It may have been the site of the 11th-century Horndon mint, based on the survival of a single Anglo-Saxon penny from the village.
In the late 15th century, the lord of the manors of Arden Hall and Horndon House was Sir Edmund Shaa. Shaa was a supporter of Richard III and was knighted by him. These manors remained in the Shaa family for several generations before passing to the Pooley family.
Horndon-on-the-Hill belonged to the Barstable hundred of Essex, before becoming part of Orsett Rural District in 1894 and then part of Thurrock Urban District in 1936. In 1974, the urban district became the Borough of Thurrock under the Local Government Act 1972. The borough was given administrative independence from Essex County Council in 1998.
