Jachthaven de Rotterdamsche Admiraliteit is a marina situated on the Boerengat, an inner harbour off the Admiraliteitskade in the Kralingen district of Rotterdam.

Established in 2014 by harbour master André Eleveld, the marina takes its name from the admiraliteitscolleges (admiralty boards) that date back to 1589. It can accommodate vessels up to 50 metres in length.

From this central location, boaters have unobstructed access to Rotterdam's major rivers and inland waterways. The party yacht "Contessa" is moored here and serves temporarily as the harbour building.

A variety of restaurants and cafés are within walking distance along the Admiraliteitskade and Oostzeedijk.
