Museumhaven is a sheltered harbour area along the Nieuwe Vaart in Amsterdam where the Vereniging Museumhaven (Harbour Museum Society) preserves and displays around 20 historical vessels.

The collection includes traditional Dutch craft such as dektjalks — flat-bottomed sailing barges suited to shallow waters — and stevenaaks, cargo ships with pointed bows built for carrying heavy loads.

Most vessels date from the late 19th and early 20th centuries and have been meticulously restored. Alongside the moored ships, old shipyard equipment is displayed on the quays, and a complimentary brochure is available to guide visitors along the waterfront.

The society's mission centres on preserving historic commercial vessels, providing facilities for their maintenance and restoration, and educating the public about traditional Dutch shipbuilding and inland waterway trade.
