The Sanigs () were a tribe inhabiting historical Heniochia, northwest shore of Kingdom of Colchis. Their ethnic identity is obscure and is the subject of a controversy. They are first attested in the works of Pliny, Arrian and Memnon of Heraclea.

Sanigs inhabited the Inner Heniochia
Georgian scholars consider them to be Zans (ancestors of Mingrelian and Laz peoples), while others maintain that they were proto-Svans. According to Arrian, they inhabited the area around Sebastopolis (modern Sukhumi). Roland Topchishvili links some modern Georgian surnames with the Sanigs (Sanikidze, Sanikiani, Sanigiani, Sanaia).
Abkhazians consider the Sanigs to be the ancestors of the Sadz and Zhaney, as evidenced by the territorial settlement of these peoples.
