Sir Ronald Macmillan Algie was a New Zealand politician who served as Speaker of the House of Representatives for six years in the 1960s. He described himself as "a Tory in the old tradition".
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 Freedom Association quickly became linked to the new National Party, and Algie became one of the party's more prominent supporters. In the 1943 elections, Algie was selected as the National Party's candidate for the electorate, controversially displacing sitting National MP Bill Endean. Algie won the seat and entered Parliament. Algie proved to be a skilled Parliamentary debater, and has been described by Hugh Templeton as the best debater of his time. Even opponents such as Bob Semple respected Algie's rhetorical abilities. He was also noted for remaining polite throughout debates, and for his willingness to apologise for any offence he accidentally gave.
After the 1949 election, when Sidney Holland formed the first National government, Algie was immediately elevated to Cabinet. He was initially appointed Minister of Education, and later became Minister of Broadcasting and Minister of Scientific and Industrial Research. 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. In the end, however, Algie's proposals for a Senate were not pursued, and New Zealand's parliament has not had an upper house since that time.
Algie briefly returned to Opposition after the 1957 election, which National lost. 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. Instead, he was convinced to take up the Speakership. He officially assumed office at the beginning of the 1961 parliamentary term. As Speaker, Algie was known for his strong insistence on politeness in debates. He also undertook a number of reforms of Parliamentary procedure to accommodate the changing nature of politics. He served six years as Speaker, retiring at the 1966 election. He was generally praised for his performance in the role and in the 1964 Queen's Birthday Honours Algie was appointed a Knight Bachelor. Algie was succeeded in the Remuera seat by Allan Highet. Algie died in Auckland on 23 July 1978.
