Lyuba Welitsch (Veličkova; Bulgarian: Люба Величкова, born 10 July 1913, Borissovo, Bulgaria - died 2 September 1996, Vienna, Austria) was a Bulgarian, later Austrian, operatic soprano.
She studied singing at Sofia Conservatory with professor Georgi Zlatev-Cherkin. After specializing in Vienna, she first appeared in Sofia in 1936. Engagements followed in Graz, Hamburg, Munich and finally at the Vienna State Opera.
Her most famous role was that of Salome, which she performed under the composer, Richard Strauss, himself in 1944 on his 80th birthday. She sang the same role for her London debut in 1947 and her first performance at the Metropolitan Opera, New York City on 4 February 1949. She also sang the title roles of Tosca and Aida, Donna Anna in Don Giovanni, Minnie in La fanciulla del West and Musetta in La bohème.
Her international career, already interrupted by the war, did not last long, although she actually continued singing until 1981. Appearances included those at the Royal Opera House, Covent Garden in the 1950s in a highly controversial production of Salome by Peter Brook with sets by Salvador Dalí. However, when her voice deteriorated she started a second career in films (in America and Austria) and on Austrian television. In 1982 she was among a number of artists on stage at Covent Garden who congratulated Dame Eva Turner at a gala for Turner's 90th birthday.
