The Hundred of Ninnes is a cadastral unit of hundred located in the Mid North of South Australia centred on the Ninnes Plain.

It is one of the 16 hundreds of the County of Daly[1] and was proclaimed by Governor Anthony Musgrave on the last day of 1874.

The majority is taken up by the bounded localities of Ninnes and Thomas Plain.

The bounded localities of Willamulka, Alford, Bute and Paskeville overlap the northwestern and southern boundaries.

Over the years the council was expanded both north and south to include more significant townships such as Bute, Alford and Kulpara.
