Warren (/ˈwɒrən/) is a common English and Irish surname and a masculine given name derived from the Norman family "de Warenne" (see De Warenne family), a reference to a place called Varenne, a hamlet near Arques-la-Bataille, along the river Varenne (Warinna in Medieval documents) in Normandy. The river name is thought to be derived from the continental Old Celtic Var- / Ver- "water, river", with a Germanic influence on the initial V- > W- after Warinna, from the Proto-Germanic war-, meaning "to protect or defend".[1][2][3]
