Sirikit (born Mom Rajawongse Sirikit Kitiyakara; 12 August 1932 – 24 October 2025) was Queen of Thailand from 28 April 1950 to 13 October 2016 as the wife of King Bhumibol Adulyadej (Rama IX).
Sirikit met Bhumibol in Paris where her father served as the Thai ambassador to France. They married in 1950, shortly before Bhumibol's coronation. In 1956, she was appointed queen regent during the King's temporary ordination as a Buddhist monk. The royal couple had four children: Ubol Ratana, Vajiralongkorn (Rama X), Sirindhorn, and Chulabhorn. As consort to the monarch who became the world's longest-reigning head of state, she held the distinction of being the world's longest-serving queen consort.
