HNLMS Van Speijk (K3, later F805) was a K-class sloop, designed in the late 1930s to replace the aging Brinio-class gunboats of the Royal Netherlands Navy.

The Kriegsmarine ordered her completion, then commissioned her for service in Norwegian and German home waters.

After the war she was repaired at the Rijkswerf at Amsterdam, then entered Dutch service as the frigate Van Speijk (F805).

The engines were rated at 3,500 brake horsepower (2,600 kW) which gave the ships a speed of 14 knots (26 km/h; 16 mph).

They carried up to 157 long tons (160 t) of fuel oil and had a complement of 106 officers and ratings.
