North Benfleet is a village and former civil parish, now in the parish of Bowers Gifford and North Benfleet, in the Basildon borough of Essex, England, located between the towns of Basildon to the west and Thundersley to the east. It adjoins the small village of Bowers Gifford and is adjacent to the town of South Benfleet. In 1931 the parish had a population of 560. On 1 January 1937 the parish was abolished to form Billericay.

The Church of All Saints is to the north of the village, about 1 mile (1.6 kilometres) north of the A13 main road and just south of the A127. Although it had fallen into disrepair after many years of disuse, it was returned to regular use in March 2013 by the Orthodox Church, and now has weekly services.

South Benfleet is a town and former civil parish, now in the unparished area of Benfleet, in the Castle Point district of Essex, England, 30 miles east of London. It is adjacent to the village of North Benfleet. The Benfleet SS7 post town includes South Benfleet, Thundersley, New Thundersley and Hadleigh. The Battle of Benfleet took place here between the Vikings and Saxons in 894. In 1951 the parish had a population of 8191.

The community is directly north of Canvey Island and is served by Benfleet railway station. It hosts South Benfleet Primary School, which was used temporarily to house local residents during the widespread flooding of 1953.

At the junction of Saint Mary's Church and The Anchor pub is the site of the UK's first "overrunable" mini roundabout.

The Battle of Benfleet took place between the Saxons and Danish Vikings in 894. This was towards the end of the Saxon period, and the Thames and other waterways made the area vulnerable to Viking attacks. Benfleet was used as a Viking base. However, the Vikings were defeated in the battle by the army of King Alfred under the command of his son Edward the Elder and his son-in-law Earl Aethelred of Mercia. Subsequently a church was built by the Saxons in thanksgiving for the victory over the Vikings. St Mary's is the most recent church building occupying this site and is a Grade I listed building.

In December 2008 a sculpture commemorating the battle was erected in Ferry Road, South Benfleet.
