Patrice Munsel (born May 14, 1925) is an American coloratura soprano, the youngest singer who ever starred at the Metropolitan Opera, nicknamed "Princess Pat".
She was born in Spokane, Washington. Munsel was coached by Giacomo Spadoni, and first sang at the Metropolitan at age 17, in March 1943. She made her official Metropolitan debut on December 4, 1943 at the age of 18, singing Philine in Mignon. Perhaps best known for the role of Adele in Die Fledermaus, she performed 225 times at the Metropolitan. Sir Rudolf Bing called her a "superb soubrette", and implied that she was the world's best, though Lily Pons performed the role of Adele in the 1950 recording of the Met production.
Munsel played the title role of Dame Nellie Melba in the film Melba (1953). She also had her own television series The Patrice Munsel Show (1956–57), and appeared on many other TV shows, including appearing in the role of Marietta d'Altena in the 1955 live telecast of the operetta "Naughty Marietta".
