The Shire of Wambo was a local government area in the Darling Downs region of Queensland, Australia. The shire surrounded but did not include the town of Dalby – which had its own municipal government. It covered an area of 5,709.7 square kilometres (2,204.5 sq mi), and existed as a local government entity from 1879 until 2008, when it amalgamated with the Town of Dalby and the Shires of Chinchilla, Murilla and Tara and the southern part of Taroom to form the Western Downs Region.
