Libuše Domanínská (née Klobásková, married Vyčichlová;[1] 4 July 1924 – 2 February 2021) was a Czech classical soprano who had a career in concert and opera from the 1940s through the 1970s.

[2] Her father was a wine expert, and her family moved from Moravia to Košice in the Slovakian part, where she first performed on a stage in an amateur theatre show at age five.

[3] Her soprano voice, described as a warm spinto "gifted in cantilena and capable of delicate expressive nuances",[1] was suitable to roles by Smetana and Janáček's Jenůfa, Káťa Kabanová and The Cunning Little Vixen.

[3] A reviewer of Gramophone wrote when it was reissued in 1995: "Libuse Domaninska is a tender Jenufa, vulnerable near the start but also in her own way deepening in human understanding as the drama develops; and her response to the music at the end, as she forgives the Kostelnicka and takes Laca, is true to Janacek's soaring melodic phrases.

"[7] She performed alongside Naděžda Kniplová as the Kostelnicka, Ivo Žídek as Steva, and Vilém Přibyl as Laca, conducted by Bohumil Gregor.
