Oshin of Korikos (or Corycos) (died 1329) served as regent of Armenia from 1320-1329. He became regent for Leo V on the death of King Oshin in 1320, whom he was rumoured to have poisoned. Oshin was also probably responsible for the deaths of King Oshin's sister Isabella of Armenia and two of her sons, in order to remove rival claimants.

Oshin married King Oshin's widow, Jeanne of Anjou. Oshin of Korikos and Jeanne had a daughter, Marie, who consectutively married two Kings of Armenia, Constantine V and Constantine VI.

Oshin and his daughter Alice (Leo's wife) were assassinated in 1329 at the behest of Leo V.
