The Shire of Glengallan was a local government area south and east of the regional centre of Warwick in the Darling Downs region of Queensland.

[2] With the passage of the Local Authorities Act 1902, it became a Shire on 31 March 1903.

On 19 March 1992, the Electoral and Administrative Review Commission, created two years earlier, produced its report External Boundaries of Local Authorities, and recommended that local government boundaries in the Warwick area be rationalised into 3 new local government areas.

The Local Government (Allora, Glengallan, Rosenthal and Warwick) Regulation 1994 was gazetted on 20 May 1994.

On 25 June, an election was held for the new council, and on 1 July 1994, the Shire of Glengallan was abolished.
