Jachthaven Zwaansmeerpolder is a large marina situated on the southern shore of the Alkmaarder- and Uitgeestermeer, east of Uitgeest in the Noord-Holland polder landscape.

Founded in 1969, it is managed by Stichting Jachthaven Zwaansmeerpolder and is by far the largest port on these lakes, offering 475 summer berths in the water and covered shed storage for around 100 boats, with additional outdoor and indoor winter storage.

The site serves as a well-equipped base for water sports enthusiasts, with on-site technical companies for boat repair and maintenance, a boat launch ramp, a laundry, restaurants, a sailing school, and boat and bike rentals.

A small campsite and camper terrain adjoin the marina, set among trees and reeds directly on the Uitgeestermeer, rounding out the recreational facilities available at this access point.
