The Prissani or Pyritzans (Polish: Pyrzyczanie) were a medieval tribe in Pomerania. They were first mentioned as "Prissani" with 70 civitas by the Bavarian Geographer, ca. 845.^[1] They are associated with the Pomeranians, and were based in the lower Oder region around the modern town of Pyrzyce (Pyritz).^[2] The mention in the Bavarian Geographer is the only written record referring to the tribe.^[2]

In the late 10th century, the Polish dukes Mieszko I and Bolesław I Chrobry subdued parts of Pomerania, but did not succeed to subdue the lower Oder region.^[3] In 1121/22, the Polish duke Bolesław III Wrymouth conquered the area along with the Duchy of Pomerania under Wartislaw I.^[4] The tribe was subsequently Christianized, missionary Otto of Bamberg celebrated the first mass baptism in Pyrzyce.^[4] A separate tribal identity, if upheld so far, vanished when it was integrated in the Duchy of Pomerania.
