Dengie /ˈdɛndʒiː/ is a scattered village and civil parish in the Maldon district of Essex, England, with a population of 119 at the 2011 census. It is about 4 km NE of the nearest town (and railway station), Southminster, on the slightly higher ground to the north of Dengie Marshes. Dengie nature reserve is about 5 km to the north-east.

It gives its name to the Dengie peninsula and hundred and to the Dengie Special Protection Area.

The place-name "Dengie" is first attested in a manuscript of between 709 and 745, where it appears as Deningei. It appears as Daneseia in the Domesday Book of 1086. The name means "Dene's island" or "the island of Dene's people".

The 14th-century church of St James is the parish church.

Dengie Flats, offshore, was used as a bombing and strafing range by the RAF and USAAF during the Second World War, and also attracted many crash-landing aircraft bound to or from the nearby RAF Bradwell Bay airfield. Between 1942 and 1945 Dengie was also the site of a 10-cm Coast Defence radar station used to warn of enemy ships and low-flying aircraft and doodlebugs.

Dengie Marshes were once used to film an episode of Doctor Who.
