The Shire of Broomehill was a local government area in the Great Southern region of Western Australia, about south of Katanning and about south-southeast of the state capital, Perth. The Shire covered an area of , and its seat of government was the town of Broomehill.
The Broomehill Road District was gazetted on 19 May 1892. On 1 July 1961, it became a shire following changes to the Local Government Act which reformed all remaining road boards into shires. On 1 July 2008, after ten months of planning and preparation, it merged with the neighbouring Shire of Tambellup to form the Shire of Broomehill-Tambellup.
The shire was originally divided into wards, but as at 2007, it was a single electorate with eight representative councillors.
