Earl De La Warr /ˈdɛləwɛər/ is a title in the Peerage of Great Britain. It was created in 1761 for John West, 7th Baron De La Warr.
The Earl holds the subsidiary titles of Viscount Cantelupe (1761) in the Peerage of Great Britain, Baron De La Warr (1572) in the Peerage of England, and Baron Buckhurst, of Buckhurst in the County of Sussex (1864) in the Peerage of the United Kingdom. The barony De La Warr is of the second creation; however, it bears the precedence of the first creation, 1299, and has done so since shortly after the death of William West, 1st Baron De La Warr.
The family seat is Buckhurst Park, near Withyham, Sussex.
The name de La Warr is from Sussex and of Anglo-Norman origin. It came probably from La Guerre, a Norman lieu-dit. This toponymic could derive from the Latin word , from the Breton or from the Late Latin warectum (fallow). The toponyms Gara, Gaire also appear in old texts cited by Lucien Musset, where the word ga(i)ra means gore. It could also be linked with a patronymic from the Old Norse .
