Dover is a toponymic surname of Celtic origin used in English and German names.

Relating to the port of Dover in Kent, England. Named from the river on which it stands, Dover is a Celtic name meaning "the waters" (from the word that later became the modern Welsh word "dwfr" for "water").^[1]

Relating to Doveren, a part of the town Hückelhoven in the Rhineland of uncertain etymology. Its origin is possibly also Celtic and thereby related in meaning to the English name as well.^[1]
