Vardan I Dadiani () (died 1213) was a Georgian noble and the forefather of the Dadiani, the princely dynasty of Samegrelo (Mingrelia), a region in western Georgia which Vardan ruled as "eristavi" ("duke") from 1183 to 1213. He was a prominent courtier of Queen Tamar of Georgia, but fell out of favor after leading an abortive rebellion in support of Tamar's disgraced former husband George the Rus' in 1191.
