Sannihit Sarovar is a sacred water reservoir in Thanesar in Kurukshetra district. It is believed to be the meeting point of seven sacred Sarasvatis. The sarovar, according to popular belief, contains sacred water. Bathing in the waters of the tank on the day of Amavasya (night of complete darkness) or on the day of an eclipse bestows blessings equivalent to performing the ashvamedh yajna.

Bathing in this sarovar is believed to offer peace to wandering and unhappy souls. Prayers and pind daan, a memorial service for the dead, is performed here. Alongside the sarovar are small shrines dedicated to Lord Vishnu, Dhruv Narayan, Laxmi Narayan, Dhruv Bhagat, Sri Hanuman and Goddess Durga. The Sannihit Sarovar is believed to be the abode of Lord Vishnu.
