The North Sea Canal (in Dutch: Noordzeekanaal) is a Dutch ship canal from Amsterdam to the North Sea at IJmuiden, constructed between 1865 and 1876 to enable seafaring vessels to reach the port of Amsterdam. It ends at Amsterdam in the closed-off IJ Bay, which in turn connects to the Amsterdam-Rhine Canal.

The drainage of the canal to the North Sea is done through the Spui Locks at IJmuiden, augmented by the largest pumping station of Europe. This system is vital to the ground water management of western Netherlands.
