Alexandra of Denmark (Alexandra Caroline Marie C******te Louise Julia; 1 December 1844 – 20 November 1925) was Queen consort of the United Kingdom of Great Britain and Ireland and Empress consort of India as the wife of King-Emperor Edward VII.

Her family had been relatively obscure until her father, Prince Christian of Schleswig-Holstein-Sonderburg-Glücksburg, was chosen with the consent of the great powers to succeed his distant cousin, Frederick VII, to the Danish throne. At the age of sixteen, she was chosen as the future wife of Albert Edward, Prince of Wales, the heir apparent of Queen Victoria. They married eighteen months later in 1863, the same year her father became king of Denmark as Christian IX and her brother was appointed to the vacant Greek throne as George I. She was Princess of Wales from 1863 to 1901, the longest anyone has ever held that title, and became generally popular; her style of dress and bearing were copied by fashion-conscious women. Largely excluded from wielding any political power, she unsuccessfully attempted to sway the opinion of British ministers and her husband's family to favour Greek and Danish interests. Her public duties were restricted to uncontroversial involvement in charitable work.
