Maria Antonina Czaplicka (October 25, 1884 - May 27, 1921), also referred to as Marya Antonina Czaplicka and Marie Antoinette Czaplicka, was a Polish cultural anthropologist who is best known for her ethnography of Siberian shamanism. Czaplicka's research survives in three major works: her studies in Aboriginal Siberia (1914); a travelogue published as My Siberian Year (1916); and a set of lectures published as The Turks of Central Asia (1919).
