Kim Edward Beazley AO (30 September 1917 – 12 October 2007) was an Australian politician who served as a member of the House of Representatives from 1945 to 1977, representing the Labor Party. He was Minister for Education in the Whitlam government from 1972 to 1975.

Beazley, the youngest of seven children, was born in Northam, Western Australia. He was the son of Alfred Beazley, a storeman and packer, and his wife Mary Wright.

Beazley grew up in Fremantle. He attended the academically selective Perth Modern School (1933–1935), where he topped the state in history and English. He went on to Claremont Teachers College, and first worked as a teacher at the Richmond State School East Fremantle, and then Arthur River, Midland Junction, and Claremont. Beazley later studied politics at the University of Western Australia (UWA), and tutored at Claremont Teachers College and at UWA. He was later to gain an MA from the Australian National University.

Beazley was active in the Labor Party, and the elegance of his writings and the eloquence of his speeches marked him out as a rising star. He served as vice president of the State School Teachers' Union and as a member of the State Executive of the Party.

On the death in office of Prime Minister John Curtin in 1945, the 27-year-old Beazley was preselected for, and won, Curtin's Federal Parliament seat of Fremantle. He was the youngest member of the federal parliament when elected, and was known as "the student prince". He became the Father of the House in 1975, and held his seat until he retired in 1977.

A committed Christian (he was brought up and baptised in the Church of Christ), and member of Moral Rearmament, Beazley was prominent on the right-wing of the Labor Party during the ideological battles of the 1950s and 1960s. He claimed a central role in the events leading to the Labor Party's fateful 1954 split and harboured lifelong regret that he failed to help avert the split when he felt it had been in his power to do so. During the leadership of Arthur Calwell (from 1960 to 1967) he was considered a possible future leader of the party, but his right-wing views, particularly his support for the U.S. Alliance, cost him support, and Gough Whitlam emerged as Calwell's successor.

Beazley was the education minister in the Whitlam government from 1972 to 1975. Though afflicted with severe illness for part of his tenure, he carried out important reforms in the education field, such as abolishing university fees and introducing needs-based funding for all schools through the Schools Commission. According to an article by C. J. Coventry, Beazley had been an informer for the U.S..

After the defeat of the Whitlam government in 1975, Beazley was elected to the Labor front bench, but resigned when it was revealed that Gough Whitlam and Bill Hartley, with the ALP national secretary, David Combe, had been seeking money from the Iraqi Ba'ath Party to pay for the party's election campaign. He retired from politics in 1977. At the time of his death he was the last parliamentary survivor of the Chifley government, as well as the earliest surviving member of the Commonwealth Parliament. He died in Perth on 12 October 2007, and was accorded a state funeral on 20 October.
