Alexandra Charles (born November 12, 1946 in Mariestad, Sweden, née Thyra Margareta Inga-Lill Gefvert) is a Swedish former nightclub owner. She ran a membership restaurant-discothèque called Alexandra's in central Stockholm from 1968 to 1988.
The clientele of her 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 her nightclub.
Charles split up with her American business partner Tom Macksey in 1976, after which her place was moved and called Alexandra. A number of Swedish show business profiles have had their debuts at Alexandra's, and she had the first Swedish version of Wild Side Story there.
Charles today also goes by her late husband's surname of Gustrin but is usually referred to by the surname of her first husband Noël Charles of Barbados. She chairs a charitable foundation and is involved in women's health issues.
