John Donald Macansh (31 May 1820 – 1 August 1896) was a member of the Queensland Legislative Council.

[2] Arriving in Australia in 1838, he worked as a clerk for the Bank of Australasia before leasing a property on the Hunter River in 1840.

[2] Macansh was elected to the Glengallan Divisional Board and then was appointed to the Queensland Legislative Council in April 1886 which he served until his death ten years later.

[1] His liberal policies had little impact with the other Legislative Council members and none of his objectives were realised.

[2] He died while attending a Glengallan Divisional Board meeting in August 1896[1] and his will, valued nominally at £241,588, was administered by a family trust that needed to be legalised by a private members bill in 1910.
