The Delftse Watersport Vereniging (DWSV), founded in 1934, is a member-based water sports association serving the Midden-Delfland area of the Netherlands.

The club maintains berths in a closed area as well as a port with direct access to open navigation water in Maasland, near Foppenplas. Additional side moorings — both exterior and covered — are available in Delft itself.

Membership is required to make use of the association's mooring, storage, and course facilities. The surrounding region is noted for its green, water-rich landscape, making it a popular base for recreational boating.
