Jachthaven Sleeuwijk is a marina on the Merwede river in the Netherlands, set amid the surrounding floodplains (uiterwaarden) of the region. The site offers views across the harbour and the wider river landscape.

Located at the marina, Brasserie Boven de Rivieren provides a waterside dining option with sightlines over the jachthaven, the uiterwaarden, and the Merwede. The brasserie serves coffee, high tea, lunch, and dinner from Wednesday through Sunday.
