Jagmal Singh was an Indian prince and court figure in the sixteenth century. He was the son of Maharana Udai Singh II and Rani Dheerbai Bhatiyani.
Even though he was not the eldest son, Dheerbai Bhatiyani, Udai Singh II’s favorite wife, wanted Jagmal to succeed him after his death. Udai Singh II designated Jagmal Singh as the Maharana’s successor on his deathbed.
In 1572, the nobility of the palace crowned Maharana Pratap instead of Jagmal as Maharana of Udaipur.
Jagmal left Mewar and joined the service of a Mughal Subedar in Ajmer, who took him in and provided him with refuge. Later, he met Akbar and was presented with the Jahazpur jagir as a gift.
He married the daughter of Maharao Man Singh II of Sirohi sometime before 1581 and became co-ruler of Sirohi in 1581. Rao Surtran, his brother-in-law, became his foe as a result of this. On the 17th of October 1583, at the Battle of Dattani, he was murdered by Rao Hammirji of Chandana.
