The Hundred of Caltowie is a cadastral unit of hundred in South Australia centred on the township of Caltowie.

[1] It is one of the 14 hundreds of the County of Victoria and was proclaimed by Governor James Fergusson in July 1871.

[2] Adjacent localities of Caltowie West and Caltowie North were officially named as such, based on the long associated names, with reference to their position within the hundred.

The only other bounded locality within the hundred is the western flank of Jamestown (that part west of the Mannanarie Hills ridge line) on the eastern side of the hundred.

The District Council of Caltowie was established in 1878, bringing local government to the hundred.
