Kulyash Baiseitova (1912–1957) was a Kazakh opera singer (lyric soprano), People's Artist of the USSR and one of the brightest stars of Kazakh opera. She was the first Kazakh singer to be awarded the title of People's Artist of the USSR, and became a symbol of the flowering of national opera art.

She was born in 1912 in the Kokshetau district (now the territory of Kazakhstan). From childhood, she showed musical talent and from a young age participated in theatrical productions. She graduated from the studio at the Kazakh Musical Theater and already in 1934, at the age of 22, she became a soloist of the first Kazakh Opera and Ballet Theater (now the Abay Theater).

She gained real fame for her role as Sarah in the opera “Birzhan and Sarah” by composer Mukan Tulebaev, where she not only demonstrated brilliant vocals, but also created a deeply dramatic image. This role became her hallmark. Among other significant works are the parts of Aizhan in “Aiman-Sholpan”, Azhar in “Abai”, Tatyana in “Eugene Onegin”. Her performance was distinguished not only by virtuoso technique, but also by deep emotional content.

Kulyash Baiseitova was one of the first Kazakh singers who presented national music on the international stage. In 1936, she performed in Moscow at the Decade of Kazakh Art, where her talent was highly appreciated. In 1937, she received the title of People's Artist of the USSR, becoming the youngest artist in history to be awarded this title.

Her life was cut short in 1957, but her contribution to the development of Kazakh opera and musical culture remains invaluable. Today, streets, theaters and music educational institutions in Kazakhstan are named after her, and her image remains an inspiration for young vocalists.
