Alasdair David Gordon Milne (8 October 1930 – 8 January 2013) was a British television producer and executive. He had a long career at the BBC, where he was eventually promoted to Director-General, and was described by The Independent as "one of the most original and talented programme-makers to emerge during television's formative years".

In his early career, Milne was a BBC producer and was involved in founding the current affairs series Tonight in 1957. Later, after a period outside the BBC, he became controller of BBC Scotland and BBC Television's director of programmes. He served as Director-General of the BBC between July 1982 and January 1987, when he was forced to resign from his post by the BBC Governors following several difficult years for the BBC, which included sustained pressure from the Thatcher government about editorial decisions which had proved controversial.

Milne was born in British India to Charles Gordon Shaw Milne, an Aberdonian surgeon, and his wife, Edith Reid (née Clark), the daughter of a headmaster of George Heriot's School. He would spend the first six years living with his maternal grandparents in Morningside, Edinburgh, until his father returned and they moved to Kent. He would go onto to study at Winchester College and New College, Oxford.

For his national service Milne was commissioned into the Gordon Highlanders, before receiving a medical discharge due to a lung infection. He joined the BBC in September 1954 as a graduate trainee after his wife spotted a BBC advertisement. He was taken under the wing of Grace Wyndham Goldie who recruited, trained, guided and encouraged many well-known BBC broadcasters and current affairs executives. Milne was one of the so-called "Goldie Boys", a group of producers and presenters, which included Huw Wheldon, Robin Day, David Frost, Cliff Michelmore, Ian Trethowan and Richard Dimbleby.

Milne was the first television producer to become Director-General. His background was in current affairs and he was a founder producer of Tonight, and became the programme's editor in 1961. He also worked on programmes such as That Was the Week That Was, one of the most controversial programmes of the 1960s, and The Great War. He was instrumental in bringing the entire Shakespeare canon to television, as well as one of the BBC's most acute comedies, Yes Minister. He would also set up BBC Scotland, when as the appointed controller in January 1968, he decided to change the lettering on the front of the building from 'BBC' to 'BBC Scotland'. According to The Herald:

"He campaigned for BBC Scotland to make programmes reflecting Scottish values and culture, believing in its obligation to support the Gaelic language"

Landmark broadcasting events during his time as Director-General included Live Aid, the massive music event precipitated by a BBC news report on famine in Africa. The BBC's new Breakfast Time programme went on air on 17 January 1983, presented by Frank Bough and former ITN newscaster Selina Scott. Milne was full of praise for the show, saying: "It was a terrific start. The first Tonight programme was not as good as this."

As Director-General, Milne was involved with a series of controversies with the British government. Contentious programme-making included the Nationwide general election special with Margaret Thatcher in 1983, the coverage of the miners' strike of 1984–85, the Panorama libel action, the reporting of the U.S. bombing of Libya and the controversy surrounding the programme Secret Society which took place in light of MI5's vetting of BBC employees.
