Rijkshaven Schoonhoven is a river access point situated on the Lek, in the town of Schoonhoven in South Holland province.

The harbor serves as a port facility along this stretch of the Lek, which forms part of the broader Nederrijn-Rhine river system in the western Netherlands.

Schoonhoven itself lies within the Krimpenerwaard municipality and is conveniently positioned within roughly 30 minutes of Rotterdam, Utrecht, and Gouda.

A regular ferry service crossing the Lek connects the town to Gelkenes on the opposite bank, providing onward access to other river destinations including Gorinchem, Dordrecht, and Kinderdijk.
