Tarsykiya Matskiv (Ukrainian: Тарсикія Мацьків; 23 March 1919 – 17 July 1944) was an ethnic Ukrainian Soviet Greek Catholic nun and martyr. Matskiv was born in Khodoriv, Lwów Voivodeship (now Lviv Oblast). She entered the Sister Servants of Mary Immaculate on 3 May 1938. She took her first vows on 5 November 1940, and worked in her convent, sewing clothes for the sisters and teaching others the skill. Even before the arrival of the Soviet Army to Lviv, she took vows before her spiritual director, Volodymyr Kovalyk, that she would give up her life for the conversion of Russia and for the Catholic Church.
