thumb|The purported Flag of Widewuto (Potrimpo on the right)
Potrimpo (also Potrimpus, Autrimpo, Natrimpe) was a god of seas, earth, grain, and crops in the pagan Baltic, and Prussian mythology. He was one of the three main gods worshiped by the Old Prussians. Most of what is known about this god is derived from unreliable 16th-century sources.
He was first mentioned (as Natrimpe) in a 1418 memorandum Collatio Espiscopi Varmiensis sent by the Bishop of Warmia to Pope Martin V.
