Countess Marie-Jenke Keglevich of Buzin (23 April 1921 – 5 October 1983) was the second wife of Albrecht, Duke of Bavaria, head of the House of Wittelsbach and pretender to the Kingdom of Bavaria from 1955 to 1996 as well as Jacobite pretender to the thrones of England, Scotland, Ireland, and France.
Wittelsbach loyalists hold that she was the rightful Queen Consort of Bavaria from 1971-83.
Jacobites consider her the rightful Queen Consort of England, Scotland, Ireland, and France during the same period.
