De Nieuwe Leeuwarder Jachthaven is a large marina situated on the Staande Mastroute in Leeuwarden, the capital of Friesland.

With nearly 700 berths in total, it holds the distinction of being the largest covered marina in Western Europe — 500 of its permanent berths are enclosed ship houses, while 150 are open berths.

Around 40 berths are reserved for visiting boaters, and space for passers-by is generally available.

The marina offers a range of onsite facilities including showers, toilets, water and electrical hookups at most berths, diesel fuel, Wi-Fi, and waste water disposal.

The historic old center of Leeuwarden is within walking distance, and both rail and bus connections are easily accessible from the harbor.
