Marko Cheremshyna (Ukrainian: Марко Черемшина) (other name: Ivan Semaniuk, Іван Семанюк), (born 13 June 1874 in Kobaky, Galicia; died 25 April 1927 in Kobaky) was a Ukrainian writer of Hutsul background.
Cheremshyna earned a law degree from the University of Vienna in 1906 and maintained a law practice in Sniatyn. He started writing short stories around 1896 and published them in newspapers and journals. Because of his birth region, Cheremshyna is often placed together with Vasyl Stefanyk and Les Martovych in the 'Pokutia triad.' However, Cheremshyna's stories differ from the other two writers significantly. He is known for his portrayals of peasant life. His works incorporate the dialect and folk themes of his birthplace. He also translated short stories into Ukrainian from German, Czech, and Hungarian.
