Tantanoola is a town in regional South Australia. The name is derived from the aboriginal word tentunola, which means boxwood / brushwood hill or camp. Tantanoola was originally named 'Lucieton' by Governor Jervois after his daughter Lucy Caroline, on 10 July 1879. It was changed by Governor Robinson to 'Tantanoola' on 4 October 1888. At the 2006 census, Tantanoola had a population of 255. The primary school closed in July 2020 after the farcical situation of having more staff than students. The remaining students transferred to nearby schools in Millicent and Mount Gambier.
