Ivan Samosenko (Ukrainian: Іван Семосенко, 1894–1920) was a Ukrainian military leader and a war criminal who was involved in anti-Jewish pogroms in Ukraine for which he was executed. However, some sources say that he was released. Before joining the Ukrainian Army, Samosenko served in the Russian Imperial Army, holding a rank of praporshchik. In 1917 he joined the newly formed Ukrainian detachment of the Russian Republic, the 2nd Ukrainian Cossack Regiment of Hetman Polubotok.
