Loosdrecht (Dutch pronunciation: [ˈloːzdrɛxt]) is a town in the municipality of Wijdemeren, North Holland, the Netherlands, with a population of about 8,600 inhabitants.

Nieuw Loosdrecht covers a small area densely populated; Oud-Loosdrecht consists mainly of lakeside villas.

Until 2002 Loosdrecht was a separate municipality in the province of Utrecht, covering the villages of Oud-Loosdrecht and Nieuw-Loosdrecht, and the hamlets of Breukeleveen and Muyeveld.

Loosdrecht is known for its lakes, the Loosdrechtse Plassen [nl], which thousands of tourists visit every year.

The lakes are a hotspot for the well-to-do, with several exclusive yachting clubs and restaurants lining the shores.
