The Boven Merwede is a stretch of river in the Netherlands. The Afgedamde Maas river joins the Waal at Woudrichem to form the Boven Merwede, which at Hardinxveld-Giessendam splits into the Beneden Merwede river on the right and the Nieuwe Merwede river on the left. Its length is 8.8 km.

There is a road bridge, from the west side of Gorinchem on the north to the west side of Sleeuwijk on the south.

There three foot passenger ferries. [1]
