The Spaarne is a river in North Holland, Netherlands. This partially canalized river connects the Ringvaart to a side branch of the North Sea Canal. It runs through Haarlem, Heemstede, and Spaarndam.
The historic canals of Haarlem's moats are connected to the Spaarne. A lock at Spaarndam separates it from the North Sea Canal.
According to Sterck-Proot, a historian, the name Spaarne probably comes from Spier, which means reed in old Dutch.
