The County of Wölpe (German: Grafschaft Wölpe) was the territorial lordship of a noble family in the Middle Ages in the Middle Weser Region near Nienburg/Weser which folded in 1302. The seat of the counts of Wölpe was the castle site at Erichshagen-Wölpe on the Wölpe stream in the borough of Nienburg in north Germany. The castle itself no longer exists.
