Nikifor Romanovich Chernigovsky (died in 1675; Polish: Nicefor Czernichowski, also known as Jaxa-Czernichowski and Czernihowski, Russian: Никифор Романович Черниговский) was a Polish noble who was exiled to Siberia over the course of the Polish-Russian war. In 1665, he murdered the voivode of Ilimsk for raping his daughter, and fled to the Amur where he reoccupied the ruins of Albazin and gathered a band of supporters, forming the state of Jaxa.
