Olympic Athletes from Russia (OAR) was the International Olympic Committee's (IOC) designation of select Russian athletes permitted to participate in the 2018 Winter Olympics in Pyeongchang, South Korea. The designation was instigated following the suspension of the Russian Olympic Committee after the Russian doping scandal. This was the second time that Russian athletes had participated under the neutral Olympic flag, the first being in the Unified Team of 1992.
