Donald Stovel Macdonald PC CC (1 March 1932 – 14 October 2018) was a Canadian lawyer, politician and diplomat.

When Pierre Trudeau announced his resignation as leader of the Liberal Party of Canada following his defeat in the 1979 election, Macdonald would have declared his candidacy for the position.

However, with the unexpected defeat of Joe Clark's Progressive Conservative government on a motion of no confidence, the Liberals asked Trudeau to lead them into the 1980 election and cancelled the leadership campaign.

The report was released in September 1985 and recommended, among other things, that Canada enter into a free trade agreement with the United States.

Macdonald married Ruth Hutchison (dec.) in 1961, and their four daughters are Leigh, Nikki, Althea, and Sonja.

Nikki Macdonald served as a senior advisor to Jean Chrétien during his time as Prime Minister.
