Bataviahaven is a harbour in Lelystad situated on the Markermeer, serving as a key access point for the surrounding lake and its attractions.

It is the primary departure point for boat services to the Markerwadden, a man-made archipelago and nature reserve located roughly four miles offshore. Kayakers and private boaters also launch from here, with an easy-access boat ramp available near parking.

The harbour caters to a wide range of watercraft, offering docks for pleasure boaters, facilities for sailing charter vessels, and infrastructure for river cruise ships. It has repeatedly been recognised as one of the best charter harbours in the Netherlands.
