Hunsingo (Gronings: Hunzego or Hunzengo) is a region in the province of Groningen, Netherlands, between the Reitdiep and Maarvliet.
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 area is largely similar to the Hoogeland region although that is more a geographical indication, while Hunsingo was an administrative unit.
The monastery of Fulda received in the ninth century a donation in Middelstum "in pago Hunergewe in regione fresonum".
In 1057 the region of "Hunsingo" is mentioned as part of a county donated by the Holy Roman Emperor Henry IV, under the regency of his mother, to the Archbishop of Hamburg, Adalbert.
The region was originally divided into two or three subdistricts, which coincided with the oldest seenddistricts (sees or mother parishes).
Of these the parishes of Usquert and Leens were the oldest: De Marne was originally part of the region Humsterland (Westerkwartier); however, the emergence of the Reitdiep and the exploitation of the underlying peat led to it becoming a separate seenddistrict.
The various districts were characterized by considerable autonomy, the joint representatives gathered in Onderdendam, that was exactly on the border of the main subdivisions.
Hunsingo has expanded by reclaiming land that initially is filled in by the natural settlement of sedimentary clay by the sea near the dikes (endiking).
