Mrinalini Devi ( born Bhabatarini Roy Choudhury; 1 March 1874[1][2] – 23 November 1902[3]) was a translator and the wife of Nobel laureate poet, philosopher, author and musician Rabindranath Tagore.

Mrinalini Devi was born to Benimadhob Roy Choudhury and Dakshayoni at Phultala village, in the then Jessore of Bengal Presidency in British India (now in Khulna, Bangladesh).

Although it is known that Rabindranath accompanied his family members from Jashore to Mrinalini Devi’s house, it is not known whether he participated in the ritual.

Taking a stroll around the western veranda of the Jorasanko, Tagore arrived at the wedding chamber as if he had travelled a long distance before finally meeting the bride.

Devendranath admitted her and Hemendranath Tagore's wife Kshinatanu to the Loreto House school to teach them English.

After studying at the school for one year, Rabindranath appointed Pandit Herambachandra Bidyaratna, a home tutor, to teach her Sanskrit.

His elder brother Birendranath's son Balendranath taught her English, Bengali and Sanskrit literature.

[4][9] On 25 October 1886, Mrinalini Devi gave birth to her first child, a daughter named Madhurilata and nicknamed Bela.
