John Dalgleish Donaldson (born 5 September 1941) is a Scottish-Australian professor and the father of Mary, Crown Princess of Denmark, the wife of the heir apparent to the throne of Denmark, Frederik, Crown Prince of Denmark.

Donaldson was born at Port Seton, Scotland, the son of Captain Peter Donaldson (1911–1978) and his wife Mary Dalgleish (1914–2002). Capt. Peter Donaldson sailed regularly on Port Seton Harbour and it is recorded that in 1962, he was on a voyage from Bass Strait Islands with a cargo of livestock, when the vessel Sheerwater was lost off Ninth Island. He and his crew were saved and there are still remains of the ship on the island today.

On 31 August 1963, John Donaldson married his first wife, Henrietta Clark Horne (1942–1997), at Port Seton. They emigrated to Tasmania, Australia, in November of that year. Donaldson's parents and his older brother Peter and younger sister Roy also emigrated to Tasmania. His father later worked as a captain for a large maritime trading company. They had four children, Jane Alison Donaldson (born 26 December 1965), Patricia Anne Donaldson (born 16 March 1968), John Stuart Donaldson (born 9 July 1970) and Mary Elizabeth Donaldson (born 5 February 1972), married in 2004 to Frederik, Crown Prince of Denmark.

In addition to British citizenship, Donaldson obtained an Australian citizenship in 1975.

Henrietta died on 20 November 1997, and Donaldson married Susan Elizabeth Horwood (born 1940) on 5 September 2001. She is a novelist and writes under the names Susan Moody, Susannah James and Susan Madison.
