Mīrā Bāī Mira Bai  ( born 1450? , Kudaki, India—died 1547? , Dwārkā Dwarka, Gujarāt Gujarat )  Hindu mystic and poet whose lyrical songs of devotion to the god Krishna are widely popular in northern India.

Mīrā Bāī Mira Bai was a Rājput Rajput princess, the only child of Ratan Singh, younger brother of the ruler of Merta. Her royal education included music and religion as well as instruction in politics and government. An image of Krishna given to her during childhood by a holy man began a lifetime of devotion to Krishna, whom she worshipped as her Divine Lover.

Mīrā Bāī Mira Bai was married in 1516 to Bhoj RājRaj, crown prince of Mewar. Her husband died in 1521, probably of battle wounds, and thereafter she was the victim of much persecution and intrigue at the hands of her brother-in-law , Ratan Singh, when he ascended the throne, and by his successor, Vikram Singh. Mīrā Bāī Mira Bai was something of a rebel, and her religious pursuits did not fit the established pattern for a Rājput Rajput princess and widow. She spent most of her days in her private temple dedicated to Krishna, receiving sādhus sadhus (holy men) and pilgrims from all over throughout India and composing songs of devotion. At least two attempts made on her life are alluded to in her poems. Once a poisonous snake was sent to her in a basket of flowers, but when she opened it, she found an image of Krishna; on another occasion she was given a cup of poison but drank it without any harm.

Finally, Mīrā Bāī Mira Bai left Mewar and returned to Merta, but finding that her unconventional behaviour was not acceptable there either, she set out on a series of pilgrimages, eventually settling in DwārkāDwarka. In 1546 Udai Singh, who had succeeded Vikram Singh as rānā rana, sent a delegation of Brahmans to bring her back to Mewar. Reluctant, she asked permission to spend the night at the temple of Ranchorji (Krishna) and the next morning was found to have disappeared. According to popular belief, she miraculously merged with the image of Ranchorji, but whether she actually died that night or slipped away to spend the rest of her years wandering in disguise is not known.

Mīrā Bāī Mira Bai belonged to a strong tradition of bhakti (devotional) poets in medieval India who expressed their love of God through the analogy of human relations—a mother’s love for her child, a friend for a friend, or a woman for her beloved. The immense popularity and charm of her lyrics lies in their use of everyday images and in the sweetness of emotions easily understood by the common people of India.
