Elżbieta Sikora (20 October 1943, Lviv) is a Polish composer. She has composed stage, orchestral, chamber, choral, vocal, and electroacoustic works as well as film scores.
Elżbieta Sikora studied piano at a music high school in Gdańsk, from which she graduated in 1963. In the same year, she began her studies at the Department of Sound Direction at the State Higher School of Music in Warsaw with Antoni Karuzas, where she received her diploma in 1968. Between 1968 and 1970, she studied electroacoustic music composition at the Groupe de Recherches Musicales (GRM) in Paris with Pierre Schaeffer and François Bayle. Upon returning to Poland, she continued her studies in composition at the State Higher School of Music in Warsaw with Tadeusz Baird and Zbigniew Rudziński. In 1973 she founded, with Wojciech Michniewski and Krzysztof Knittel, the Group of Composers KEW. She obtained her second degree, from the Department of Composition, in 1977. 
Since 1981 she has been living in France. She participated in a computer music course at the Parisian IRCAM. On commission from the Centre Pompidou for IRCAM, she wrote La tête d’Orphée II (1981–1982) for flute and electronic instruments, in which the tape part was realized utilizing, among other things, a 4x digital processor, Buchla synthesizer and PDP-10 computer. It was not only her first work for instrument with electronics, but also her first attempt at work with a computer (which was at the time the size of a wardrobe). 
She received numerous honors including First Prize in the GEDOK competition in Mannheim (1981, for Guernica, hommage à Pablo Picasso), the Prix de la Partition Pédagogique and the Prix Stéphane Chapelier-Clergue-Gabriel-Marie, both from SACEM (both 1994) and the SACD Prix Nouveau Talent Musique (1996, for L’Arrache-coeur). 
From 1985 to 2005 Elzbieta Sikora thought at the Music Conservatory and at the Fine Art School in Angoulême. In 2004 and 2007 she was visiting professor at the University of Chicago. From 2011 to 2017 Elzbieta Sikora was artistic director of Musica Electronica Nova Festival, Wroclaw, Poland.
