Donald Macdonell

Donald Macdonell (1862 – 26 October 1911) was a politician, trade unionist and shearer in New South Wales, Australia.

Born at Stuart Mill near St Arnaud, Victoria, to Christina McMaster and Alexander Macdonell, a Scottish-born farmer and shearer. He helped on his father's farm as a child and moved to New South Wales in 1886, being an early member of the Australian Shearers' Union. He played a leading role in the 1891 strike, when he traveled to Queensland. He became secretary of the Shearers' Union's Bourke branch and a member of the Labor Party in 1894, and helped to draft the rules for the new Australian Workers' Union. In the same year the shearers' and labourers' unions amalgamated . He continued as secretary of the AWU's Bourke branch thereafter. He was the general secretary of the AWU from 1900 to 1911. He was Minister for Agriculture and Chief Secretary in the McGowen ministry from 1910 to 1911.

He was a friend of Henry Lawson who, in 1899, described Macdonell as "the tallest, straightest, and perhaps the best of the Bourke-side bush-leaders".
