Maharawal Samarsimha or Maharawal Samar Singh was the ruler of the Guhila dynasty from 1272 to 1301. He was the son of Rawal Tejasimha and father of Ratnasimha.^[1]

He assisted the ruler of Gujrat, Sarangdeva Baghela against a Turkish Invasion. This Turkish invader is speculated to be Ghiyas ud din Balban or Alauddin Khalji.^[2]

If the invader was Alauddin Khalji, then his motives for invasion would not be devastation or annexation but passage to invade Gujrat. Alauddin was refused passage from Marwar , so the passage was drawn from Mewar. Samarsimha offered strong resistance from Mewar but Alauddin was able to do minor attack on Hindu shrines. but no major devastation was found.^[3]
