Alexandra Charles (born 12 November 1946, née Thyra Margareta Inga-Lill Gefvert) is a Swedish former nightclub owner. With her first husband Noël Charles (1940-2013) she opened a membership restaurant-discothèque called Alexandra's in central Stockholm in 1968 which existed in four successive central locations in that city until 1988. They also initially had a club by the same name in his native Barbados.
The clientele of the Stockholm club included Swedish celebrities and royalty, with regulars including ABBA, Björn Borg and King Carl XVI Gustaf. Many international celebrities who visited Stockholm were also visitors to Charles's nightclub.
Alexandra Charles was born in Mariestad, Sweden. In 1976, after her divorce from Noël Charles, she split up with her American business partner Tom Macksey, and her business was moved and renamed Alexandra. A number of Swedish show business profiles had made their debuts at Alexandra's, and the first Swedish version of Wild Side Story played there.
Charles has been married twice more but still goes by the surname of her first husband (who later married Cynthia Lennon). She chairs a charitable foundation and is involved in women's health issues.
