Magda Lupescu (born 1896?, Iaşi, Rom.—died June 28/29, 1977, Estoril, Port.) was a Romanian adventurer who, as mistress of King Carol II of Romania, exerted a wide-ranging influence on Romanian public affairs during the 1930s.
The facts concerning her early life are uncertain, but it is known that her father was Jewish and her mother Roman Catholic. She was evidently married to an army officer named Tampeanu when, in the early 1920s, she began her liaison with Prince Carol, the heir-apparent to the Romanian throne. When Carol refused to end the relationship, he was forced to renounce his rights of succession and go into exile (1925). He later agreed to end the affair and became reconciled with his former wife, Princess Helen of Greece, in order to reclaim his crown; but in 1930, shortly after his return to Romania as king, he installed Lupescu in Bucharest.
She soon came to wield an influence that was considered stronger than that of any government minister. The National Peasant Party leader Iuliu Maniu railed against the “sinister Jewish influence at the palace” that was “responsible for almost every evil in this country.” Her Jewish origins marked her especially for vilification by the principal Romanian fascist organization, the Iron Guard. She fled the country with Carol after his abdication in September 1940. Upon her marriage to the former king in July 1947, he conferred on her the title Princess Elena. After the death of Carol (1953) she continued to live in Estoril, Port.
