Cerf or Le Cerf is a French-language surname, derived from cerf, meaning "hind", "hart" or "deer". It is common for both Christians^[1] and Jews, an equivalent of Naphtali, to which the meaning of "hind" is attributed, and is thus also the equivalent of the same name translated into other European languages, for example Hirsch in German and Jellinek in Czech.
