De Uitkijk is a marina and water-sports hub situated on the Eerste Plas of the Loosdrechtse Plassen in Oud-Loosdrecht, Noord-Holland.

Established in 1936, it has undergone a thorough renovation, with fully updated docks offering around 180 permanent berths and a modest number of visitor spaces. The marina serves as a central access point to the open water of the plassen.

Beyond moorings, De Uitkijk is home to several recreational operators offering sailing lessons, SUP, wingfoiling, and wakeboarding, making it a lively base for a range of water sports. A café-bistro on site rounds out the facilities.

Note that permanent berths are the primary offering; visiting boaters are directed to the adjacent public Porseleinhaven.
