Meera, better known as Mirabai, and venerated as Sant Meerabai, was a 16th-century Hindu mystic poet and devotee of Krishna. She is a celebrated Bhakti saint, particularly in the North Indian Hindu tradition. She is mentioned in Bhaktamal, confirming that she was widely known and a cherished figure in the Bhakti movement by about 1600. In her poems, she expressed madhurya bhava towards Krishna.

Most legends about Mirabai mention her fearless disregard for social and family conventions, her devotion to Krishna, and her persecution by her in-laws for her religious devotion. Her in-laws never liked her passion for music, through which she expressed her devotion, and they considered it an insult to the upper caste people. It is said that amongst her in-laws, her husband was the only one to love and support her in her Bhakti, while some believed him to have opposed it. She has been the subject of numerous folk tales and hagiographic legends, which are inconsistent or widely different in details. According to legend, when her in-laws attempted to murder her with poison, Mirabai tied a sacred thread on a murti of Krishna, trusting in His divine protection, through which she was saved by divine intervention. This legend is sometimes cited as the origin of the ritual of tying rakhi on Krishna's murti.

Millions of devotional hymns in passionate praise of Krishna are attributed to Mirabai in the Indian tradition, but just a few hundred are believed to be authentic by scholars, and the earliest written records suggest that except for two hymns, most were first written down in the 18th century. Many poems attributed to Mirabai were likely composed later by others who admired Mirabai. These hymns are a type of Bhajan, and are very famous across India.

Some Hindu temples, such as one within Chittor Fort, are dedicated to Mirabai's memory. Legends about Mirabai's life, of contested authenticity, have been the subject of movies, films, comic strips and other popular literature in modern times.

Primary records about Meera are not available, and scholars have attempted to establish Meera's biography from secondary literature that mentions her.

Mirabai was born into a Rathore Rajput royal family in Kudki (modern-day Beawar district of Rajasthan), and spent her childhood in Merta. She was the daughter of Ratan Singh Rathore and grand daughter of Rao Dudaji of Merta, thus making her a great-granddaughter of Rao Jodha and a cousin of Jaimal Rathore.

Meera had an arranged marriage with Bhoj Raj, the crown prince of Mewar, in 1516. Her husband was wounded in one of the ongoing wars with the Delhi Sultanate in 1518, and he died from battle wounds in 1521. Both her father and father-in-law (Rana Sanga) died a few days after their defeat in the Battle of Khanwa against Babur, the first Mughal Emperor.

After the death of Rana Sanga, Vikram Singh became the ruler of Mewar. According to a popular legend, her in-laws tried to assassinate her multiple times. These attempts included sending Meera a glass of poison and telling her it was nectar, and sending her a basket with a snake instead of flowers. According to hagiographic legends, she was not harmed in either case, with the snake miraculously becoming, depending on the version, a Krishna idol or a garland of flowers. In another version of these legends, she is asked by Vikram Singh to drown herself. When she attempts to do so, she merely floats on the water. Yet another legend states that the third Mughal emperor, Akbar, came with Tansen to visit Meera and presented her with a pearl necklace. Scholars doubt this happened, as Tansen joined Akbar's court in 1562, 15 years after Meera's death. Similarly, some stories state that Ravidas was her guru (teacher), but there is no corroborating historical evidence for this.
