Mehtab Kaur (née Mohinder Kaur; 14 September 1922 – 24 July 2017), was the second wife of the ninth and the last Maharaja of Patiala Yadavindra Singh (1914–1974). She was the mother of Amarinder Singh, the current Chief Minister of Punjab. Had it not been for the erstwhile Indian princely families being stripped of their titles in 1971, upon the death of her husband she would have been considered Rajmata (queen mother), and in popular usage is commonly referred to as such.
