She was 88 and survived by a daughter. Considered as the queen of Thumri and fondly called Appa ji, Girija Devi was taken to the city's BM Birla Heart Research Centre on Tuesday afternoon with cardiovascular ailments.
She was put on life support, her family sources said.
"Girija Devi's condition was quite critical when she was brought to the hospital. She was admitted to the CCU and was under constant watch. But she passed away at around 8.45 pm," hospital spokesperson told PTI.
Prime Minister Narendra Modi condoled her death, saying the singer's music appealed across generations and her pioneering efforts to popularise Indian classical music would always be remembered.
'Saddened by demise of Girija Devi ji. Indian classical music has lost one of its most melodious voices. My thoughts are with her admirers,' he tweeted.
A legendary singer of the 'Benaras gharana' had received Padma Shri in 1972, Padma Bhushan in 1989 and the Padma Vibhushan in 2016.
Born in a zamindar family at a village near Banaras (Varanasi) on May 8, 1929, music was a part of Girija Devi's life from a very early age.
