Welwyn /ˈwɛlɪn/ is a village and civil parish in Hertfordshire, England. The parish also includes the villages of Digswell and Oaklands. It is sometimes called Old Welwyn to distinguish it from the newer settlement of Welwyn Garden City, about a mile to the south, though many residents object to the suggestion of inferiority or irrelevance that tends to be implied by the moniker "Old".
The name is derived from Old English welig meaning "willow", referring to the trees that nestle on the banks of the River Mimram that flows through the village. The name itself is an evolution from weligun, the dative form of the word, and so is more precisely translated as "at the willows", unlike nearby Willian which is likely to mean simply "the willows". In having its name derived from welig rather than sealh (the more commonly cited Old English word for willow), Welwyn perhaps shares an etymology with the estate of Heligan in Cornwall whose name is derived from helygen, the Cornish word for willow.
