Mata Sunder Kaur (Mata Sundri) was the wife of Guru Gobind Singh (1666-1708). She was the daughter of Bhai Ram Saran, a Kumarav Khatri of Bajwara, in present-day Hoshiarpur district of the Punjab. She was married to the tenth Sikh Guru at Anandpur on 4 April 1684. The father-in-law had desired that the bridegroom should come at the head of a marriage party to Lahore where the ceremony should be performed with due dignity.

       Four sons were born to Mata Jito/Sundar - Baba Ajit Singh (b:11 February 1687), Baba Jujhar Singh (9 April 1691), Baba Zorawar Singh (28 November 1696) and Baba Fateh Singh (12 December 1699). Mata ji received Amrit at the 1699 Vaisakhi Amrit Sanchaar ceremony and adopted the name 'Sunder Kaur'.
