The Hundred of Barunga is a cadastral unit of hundred located in the Mid North of South Australia on the approximate area of the Barunga Range, centred on Bald Hill.

[2] It was named in 1869 by Governor James Fergusson[1] after an indigenous term meaning gap in the range.

[1] See Barunga Range § Etymology The following localities and towns of the Wakefield Council area are situated inside (or largely inside) the bounds of the Hundred of Barunga: On 5 January 1888 the District Council of Snowtown was established, along with many other new local government bodies in South Australia, by the District Councils Act 1887,[3] incorporating the entirety of the hundreds of Barunga and Boucaut.

In 1987 Barunga and Snowtown wards of the Snowtown council retained their statuses as a ward in the consolidated District Council of Blyth-Snowtown.

Since the amalgamation of Blyth-Snowtown and Wakefield Plains councils into the new Wakefield Regional Council the hundred has been a part of the much larger North ward of the Wakefield council.
