The Hundred of Tungkillo is a cadastral unit of hundred in the southeastern foothills of the Mount Lofty Ranges. One of the 10 hundreds of the County of Sturt, it was proclaimed on 7 August 1851 by Governor Henry Young. According to local historian Geoff Manning, the place name is derived from tainkila an indigenous term used by the Peramangk people meaning ghost moth grubs which was first applied to Tungkillo mine, about south of the township of Palmer in the east of the hundred.
