The Shire of Greenough was a local government area in the Mid West region of Western Australia, 420 kilometres (261 mi) north of the state capital, Perth surrounding the city of Geraldton.

The Shire covered an area of 1,752 square kilometres (676.5 sq mi), and its seat of government was the outer Geraldton suburb of Utakarra.

The Greenough electors successfully petitioned for a referendum to determine whether amalgamation should proceed.

This was held on 2 December 2006, and with a participation rate of 28.74%, a majority of 80% voted against the proposal.

[3] However, under the Local Government Act 1995 (clause 10 of Schedule 2.1) as the vote did not attract 50% of registered voters, it did not meet the requirements for a valid poll.
