Mehraj is a town in the Bathinda district of Punjab. Mehraj was founded in 1627 by Bhai Mohan (d. 1630), a Jatt of the Siddhu clan, with the help of Sri Guru Hargobind Ji.

According to Sikh tradition, Bhai Mohan and his family wanted to settle down in this area but the Bhullars, the local dominating tribe, resisted.

Mohan sought Guru Hargobind's blessing and succeeded in founding a village which he called Mehraj after the name of his great-grandfather.

The Bhullars tried to dislodge him, but were driven away with Guru Hargobind's help.

The Battle of Gurusar was the third battle fought by Sri Guru Hargobind Sahib Ji near Mehraj with Lala Beg and Qamar Beg in 1631. Despite overwhelming odds, the mughals were completely crushed in this battle.
