The Shire of Maroochy was a local government area about 100 kilometres (62 mi) north of Brisbane in the Sunshine Coast region of South East Queensland, Australia.

The shire covered an area of 1,162.7 square kilometres (448.9 sq mi), and existed as a local government entity from 1890 until 2008, when it amalgamated with its neighbours to the north and south to form the Sunshine Coast Region.

On 15 August 1986 a fire damaged this beyond repair—it was bulldozed three years later to make way for the new Centenary Square development.

In 2000, Queensland police arrested a man for using a computer and a radio transmitter to take control of the Maroochy Shire wastewater system and release sewage into parks, rivers and property.

On 15 March 2008, under the Local Government (Reform Implementation) Act 2007 passed by the Parliament of Queensland on 10 August 2007, the Shire of Maroochy merged with the Shire of Noosa and the City of Caloundra to form the Sunshine Coast Region.
