Mingbool is a locality in the Australian state of South Australia located about 372 kilometres (231 mi) south-east of the state capital of Adelaide adjoining the border with the state of Victoria and about 16 kilometres (9.9 mi) north-west of the municipal seat of Mount Gambier.

[1][4] Boundaries for the locality were created in February 1999 for the “long established name.”[1][3] Its name is derived from the cadastral unit of the Hundred of Mingbool and ultimately from an aboriginal word for “water.”[10] Mingbool's western boundary aligns with the route of the Riddoch Highway while its eastern boundary is the state border.

[1] The principal land use in the locality is primary production.

Two parcels of land in its south-west corner located close to both the Riddoch Highway and the Mount Gambier Airport in the adjoining locality of Wandilo are zoned for industrial purposes.

[13] Mingbool is located within the federal division of Barker, the state electoral district of Mount Gambier and the local government area of the District Council of Grant.
