Angus Charles Drogo Montagu, 12th Duke of Manchester (9 October 1938 – 25 July 2002) was a British hereditary peer. Until he inherited the dukedom in 1985, he was known by the courtesy title of Lord Angus Montagu.

Angus grew up in Britain, Ceylon and Kenya. After serving the Royal Marines, he settled in Australia and had a number of jobs. During middle age, he suffered from financial hardship and fell victim to a number of confidence tricks for which he took the blame. He was known for his friendly and outgoing personality, and his few speeches in the House of Lords were viewed positively.

Angus was born on 9 October 1938 as the son of Alexander Montagu, 10th Duke of Manchester, and Nell Vere Stead, and was the younger brother of Sidney Montagu, 11th Duke of Manchester. He was born in the family seat of Kimbolton Castle near Bedford but moved frequently during childhood, including spending time in Singapore and Ceylon including a period in a convent in the latter. He did not enjoy his time there, later saying the nuns "weren't very pleasant people".

In 1950, he joined his father in Kenya for a short period after Kimbolton was sold. He had a good relationship with his mother, who enjoyed looking after young children, and was spoiled as a result. After trying the local school in Keyna, but was bullied and stopped going, and consequently had no regular formal education until he was eleven. He was subsequently educated at Traddur Housea, a Welsh prep school and Gordonstoun School, Moray, Scotland, returning each summer to Kenya to spend time with his family. He left school in 1956 without any qualifications and began service in the Royal Marines, boarding HMS Loch Fyne in January 1957. He was the only public-school educated man on the ship and did not get on well with his fellow recruits.
