Astrid of Sweden (17 November 1905 – 29 August 1935) was the Queen of the Belgians and the first wife of King Leopold III. Originally a princess of Sweden of the House of Bernadotte, Astrid became the Duchess of Brabant after her marriage to Leopold in November 1926. She was Queen of the Belgians from 23 February 1934 until her death. Her charity work focused particularly on women and children.
Astrid's only daughter, Joséphine-Charlotte, later became Grand Duchess consort of Luxembourg, while both her sons reigned as King of the Belgians. Astrid was also a sister of Crown Princess Märtha of Norway (wife of King Olav V) and a maternal aunt of King Harald V of Norway.
