Aanlegplaats De Keur is a mooring point located at De Put, a recreational harbour on the Haringvliet in the Netherlands.

De Put itself originated as a clay pit excavated for dike repairs following the catastrophic flood of 1953, and was gradually transformed into a marina during the 1970s and 1980s.

The harbour is home to Watersportvereniging De Put, a sailing and watersports club founded in March 1978. This landing point provides water access within the club's scenic harbour setting.
