Rijkshaven Keizersveer is a harbor access point situated on the Bergsche Maas, the canal branch of the river Maas constructed in 1904 in the Dutch province of North Brabant.

The Bergsche Maas runs from Heusden to the Amer estuary near Geertruidenberg, connecting also to the river Donge and the Oude Maasje.

The area around Keizersveer has served as a notable water monitoring and abstraction location on the Bergsche Maas, valued because the river here carries exclusively Meuse water, making it a useful reference point for river water quality.

An artwork is also recorded in the vicinity of the harbor.
