Maharani Chimnabai I (1864 – 7 May 1885) was a queen and the first wife of Maharaja Sayajirao Gaekwad III of the princely state of Baroda (now in Gujarat), British India.

Lakshmibai, along with her two sisters, were adopted by princess Vijaya Mohana (1845–1885) who was the daughter of Sivaji, the last Maharaja of Tanjore.

[1] She changed her name to Chimnabai I when she married Sayajirao Gaekwad III of Baroda State on 6 January 1880.

[3] The foundation stone of the present royal residence of the Gaekwad family was laid by Sayajirao and Chimnabai.

[1] "I wish to commemorate the virtues of Her Late Highness and the admiration I entertained for her-the mild, charitable, amiable woman, the devoted mother and loving wife."

[15][16] As Chimnabai had died due to pregnancy-related complications, a hospital was built in 1885 in Baroda by Sayajirao for the well-being and safe delivery of other women of the state.
