The Arumer Zwarte Hoop, meaning "Black Heap of Arum" (West Frisian: Swarte Heap) was an army of peasant rebels and mercenaries in Friesland fighting against the Habsburg authorities from 1515 to 1523. For 4 years they were successful under the former farmer Pier Gerlofs Donia. Led by his Lieutenant Wijerd Jelckama from 1519 they slowly lost ground and were captured and executed in 1523.

The leader was the farmer Pier Gerlofs Donia, whose farm had been burned down and whose kinfolk had been killed by a marauding landsknecht regiment. Since the regiment had been employed by the Habsburg authorities to suppress the civil war of the Vetkopers and Schieringers, Donia put the blame on these authorities. After this he gathered angry peasants and some petty noblemen from Frisia and Gelderland and formed the Arumer Zwarte Hoop.
