The Shire of Heywood was a local government area about 360 kilometres (224 mi) west-southwest of Melbourne, the state capital of Victoria, Australia. The shire covered an area of 3,764 square kilometres (1,453.3 sq mi), and existed from 1856 until 1994.

It was, for most of its life, known as the Shire of Portland.

Heywood was first incorporated as the Portland Road District on 25 January 1856, which became the Shire of Portland on 8 December 1863. On 23 April 1958 and 31 May 1968, it lost parts of its area to the Town of Portland, and on 1 October 1988, it was renamed the Shire of Heywood.^[2]

On 23 September 1994, the Shire of Heywood was abolished, and along with the City of Portland and most of the Shire of Glenelg, was merged into the new Shire of Glenelg.^[3]
