The Brinio-class (sometimes referred to as Gruno-class) was a class of three gunboats built by the Rijkswerf in Amsterdam for the Royal Netherlands Navy. The class comprised Gruno, Brinio and Friso.

All ships were still in service at the start of World War II. Only Gruno was able to escape to the United Kingdom. Friso was sunk by German bombers on 12 May 1940 on the IJsselmeer and Brinio was scuttled by her own crew on the IJsselmeer on 14 May 1940 after being damaged by a German aircraft.
