Iultin (Russian: Иультин; Chukchi: Ивылтин) was an urban-type settlement in Chukotka Autonomous Okrug, part of the Far Eastern Federal District of Russia. As of 2010 the area is uninhabited, but only thirty-five years ago it had a population of 3,120 (1989 Soviet census). The settlement was established to house the workers and administrative staff of the tin and tungsten mines, with transport connections with the port, Egvekinot being constructed by Gulag prisoners. The settlement was abolished in 1995, when mining activities became no longer profitable.
