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

It is the main departure point for boat services to the Markerwadden, a man-made archipelago and nature reserve located roughly four miles offshore. Kayakers also use the harbour's boat launch to paddle out across the Markermeer.

The harbour accommodates a wide range of watercraft, from private pleasure boats to large sailing charter vessels and river cruise ships.

It offers docking facilities with both low and high berths, and has repeatedly been recognised as one of the leading charter harbours in the Netherlands.
