Hunsingo ( Gronings: Hunzego or Hunzengo) is a region in the province of Groningen, Netherlands, between the Reitdiep and Maarvliet. Hunsingo was one of three Ommelanden. It is bordered to the north by the Wadden Sea, to the east Fivelingo, in the west to the Westerkwartier and Friesland and in the south, Gorecht. The region corresponds to the current municipalities De Marne, Eemsmond, the majority of the municipalities of Bedum and Winsum and the former municipality of Middelstum.
The name means area (go or gau) of the Hunze River. The Hunze no longer exists after the construction of the Reitdiep canal. Originally the Hunze followed a different course with its mouth at Pieterburen on the Wadden Sea, and divided Hunsingo into two parts.
Hunsingo was the first member of the Ommelander Union. The main town was Winsum where the Ommelanden for a short time held their own meetings. The area is largely similar to the Hoogeland region although that is more a geographical indication, while Hunsingo was an administrative unit.
The three Wadden islands of Rottumerplaat, Rottumeroog and Zuiderduintjes belong to this area.
