Maharani Jindan Kaur was the last queen of the Sikh Empire from 1843 until 1846. She was the youngest wife of the first Maharaja of the Sikh Empire, Ranjit Singh, and the mother of the last Maharaja, Duleep Singh.

Maharani Jind Kaur (c. 1817 – 1 August 1863) was regent of the Sikh Empire from 1843 until 29 March 1847. After the Sikh Empire was dissolved on 29 March 1847 the Sikhs claimed her as the Maharani and successor of Maharaja Duleep Singh. However, on the same day the British took full control and refused to accept the claims.

She was the youngest wife of the first Maharaja of the Sikh Empire, Ranjit Singh, and the mother of the last Maharaja, Duleep Singh. She was renowned for her beauty, energy and strength of purpose and was popularly known as Rani Jindan, but her fame is derived chiefly from the fear she engendered in the British in India, who described her as "the Messalina of the Punjab".
