Ivan Petrizhitsky-Kulaga,[1] also Petrazhytsky-Kaluha[2] (Ukrainian: Іван Петражицький-Кулага; ca. 1570 – 1632) was a Cossack hetman in the years 1631–32. Seen as a supporter of the Polish–Lithuanian Commonwealth, he was stripped of his hetman position in an internal Cossack conflict and executed in 1632.
