Chand Kaur (1802 – 11 June 1842) was the regent of the Sikh Empire, proclaimed as Malika Muqaddisa (lit. Queen Immaculate) on 2 December 1840. She was born to Sardar Jaimal Singh of the Kanhaiya Misl. In 1812, she was married to Crown Prince Kharak Singh, son and heir apparent of Maharaja Ranjit Singh and Maharani Datar Kaur. In 1821 she gave birth to their only son Nau Nihal Singh, who became second in line of succession to the throne of Punjab.
During her husband's brief reign she served as the queen consort of the Sikh Empire and became the Rajmata when her son ascended the throne.
After the deaths of both her husband Kharak Singh and son Nau Nihal Singh, she declared herself regent for the unborn child of Nau Nihal Singh and his pregnant widow Sahib Kaur. She abandoned her claim when Sahib Kaur delivered a stillborn son and rival Sher Singh led a successful assault of Lahore.[1] She was later murdered by her servants on 11 June 1842.[1]
