The Rijkshaven Oosterhout is an access point situated on the Wilhelminakanaal in the Dutch province of North-Brabant.

The Wilhelminakanaal is a 68-kilometer canal completed in 1923, running from the Zuid-Willemsvaart near Laarbeek westward to the Amer (Meuse) just west of Geertruidenberg.

Oosterhout sits at a notable transition point on the canal: the section from the Amer southward to Lock I in Oosterhout accommodates larger vessels up to CEMT class Va (135 × 11.

5 × 3 m), while the section continuing south toward Tilburg is rated CEMT class IV, handling ships up to 90 × 9. 60 × 2. 70 m. This makes the Rijkshaven a strategically positioned access point near the boundary between these two navigation classes.
