Sir Ronald Macmillan Algie (22 October 1888 – 23 July 1978) was a New Zealand politician who served as Speaker of the House of Representatives for six years in the 1960s.

[1] On 4 December 1917 at St Mary's pro-Cathedral, Parnell, Algie married Helen Adair McMaster,[3] a prominent alpinist whose climbs included an ascent of Aoraki / Mount Cook.

[4] In 1937, Algie became the director of the Freedom Association, an organisation which strongly opposed the left-wing Labour Party government of the time.

The incumbent MP for Remuera was National's Bill Endean who was unpopular among supporters, so much so that he was nearly deselected for the planned 1941 general election.

[7] He also co-led the committee that looked into the future of the Legislative Council, the upper house of the New Zealand Parliament, which was abolished from 1951.

[9] When National regained power after the 1960 election, Algie is believed to have wanted the post of Minister of External Affairs, but was not given it (possibly because of his age; he was seventy-two).

He was generally praised for his performance in the role and in the 1964 Queen's Birthday Honours Algie was appointed a Knight Bachelor.
