Maria Antonina Czaplicka (25 October 1884 – 27 May 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).
Curzon Press republished all three volumes, plus a fourth volume of articles and letters, in 1999.
