Gurdwara Mata Kaulan Sahib or Gurdwara Kaulsar Sahib is a sacred Sikh shrine on the west-side of Gurdwara Baba Atal in Amritsar, Punjab near the main Darbar Sahib at Harmandar Sahib.
The significance of Gurdwara Mata Kaulan and Kaulsar sarovar could be adjudged from the fact that Guru Hargobind, the sixth Sikh guru, had directed the devotees to take a dip in the Sarovar Kaulsar before the Golden Temple sarovar.
