Valya Mladenova Balkanska (Bulgarian: Валя Младенова Балканска; born 8 January 1942) is a Bulgarian folk music singer from the Rhodope Mountains known locally for her wide repertoire of Balkan folk songs, but in the West mainly for singing the song "Izlel ye Delyo Haydutin", part of the Voyager Golden Record selection of music included in the two Voyager spacecraft launched in 1977.
Born as Feyme Kestebekova (Bulgarian: Фейме Кестебекова) in a Pomak family in a hamlet near the village of Arda, Smolyan Province, Balkanska has been singing Rhodope folk songs since her early childhood.
Balkanska has been working with the Rodopa State Ensemble for Folk Songs and Dances from Smolyan, of which she is a soloist, since 1960.
Balkanska is most famous in the West for "Izlel ye Delyo Haydutin", which she recorded in 1968 accompanied by the bagpipe (gaida) players Lazar Kanevski and Stephan Zahmanov.
Her best-known recording was made in the late 1960s by the American explorer of Bulgarian folklore Martin Koening and was released on vinyl in the United States.
