Yakiv Barabash () was a Zaporozhian Cossack Otaman (1657–58) who opposed Hetman Ivan Vyhovsky. In 1657 he and Poltava polkovnyk Martyn Pushkar led a pro-Muscovy revolt against Vyhovsky, who was generally pro-Polish in his policies. The revolt ended in June 1658 near Poltava, when Vyhovsky and his cossacks defeated the rebellion. Barabash was later captured and executed for his crimes.
