Ossip Iliych Runitsch (Russian: Осип Ильич Рунич, IPA: [ˈosʲɪp ɨˈlʲjitɕ rʊˈnʲitɕ]; born Osip Fradkin, 1889 – 6 April 1947) was a Russian silent film actor, producer and stage director.

Runitsch was a long time admirer of his co-star Kholodnaya and after her death in 1919 during Russian Civil War, he fled Russia and left for Italy where he took part in a number of films.

Later, he moved to Germany where he starred together with Emil Jannings and other famous German actors.

By the late 1930s, he was living in Riga, Latvia, where he played in the troupe of Russian Drama Theatre.

Apparently, when he realised that the World War II was inevitable, he accepted an invitation to tour South Africa from his local Jewish friends.
