The City of Moreton Bay, known until July 2023 as the Moreton Bay Region, is a local government area in the north of the Brisbane metropolitan city in South East Queensland, Australia. Established in 2008, it replaced three established local government areas, the City of Redcliffe and the Shires of Pine Rivers and Caboolture.

The Shire of Caboolture was a local government area located in the Australian state of Queensland on the northern urban fringe of the capital, Brisbane, and south of the Sunshine Coast. The Shire covered an area of 1,224.4 square kilometres (472.7 sq mi), of which approximately one-quarter was urban, and existed as a local government entity from 1879 until 2008, when it amalgamated with the City of Redcliffe and Shire of Pine Rivers to form the Moreton Bay Region, which was renamed the City of Moreton Bay in July 2023.
