Colin Christopher Paget Tennant, 3rd Baron Glenconner (1 December 1926 – 27 August 2010), was a British peer, landowner and socialite. He was the son of Christopher Tennant, 2nd Baron Glenconner, and Pamela Winifred Paget. He was also the nephew of Edward Tennant and Stephen Tennant, and the half-brother of the novelist Emma Tennant.
Before succeeding to the peerage in 1983, he had travelled widely, especially in India and the West Indies. He was an avid socialite and a close friend of Princess Margaret, to whom his wife, the former Lady Anne Coke, was a lady-in-waiting. In 1958, he purchased the island of Mustique in The Grenadines for £45,000.
