Pogesanians are one of the eleven Prussian clans mentioned by Peter von Dusburg.

The clan lives in Pogesania, a small territory stretched between the Elbląg and Pasłęka rivers.

It is now located in the Warmian-Masurian Voivodeship, northern Poland.

Pogesanians, as the rest of the Prussians, are conquered by the Teutonic Knights and become Germanized or polonized.

The old Prussian language becomes extinct sometime in the 17th century.
