The Hundred of Booyoolie is a cadastral unit of hundred in South Australia. It is one of the 14 hundreds of the County of Victoria and was proclaimed by Governor James Fergusson in July 1871. The hundred includes the towns of Gladstone, Laura and within its bounds. It was named for Booyoolie Station, the homestead for which was located immediately west of the present township of Gladstone. The source of the station name is unclear. It may have been named for an indigenous phrase meaning "boiling up smoke cloud" but this supposed etymology lacks contemporary corroboration. Official sources suggest the name was a settler invention formed from the words "beau ewe lea".
