Raja Prithviraj Singh I (? –1527), also known as Prithvi Singh I, was the 16th-century Kachwaha Rajput ruler of Kingdom of Amber. He was a monarch of strong religious inclinations and during his reign, the Kingdom of Amber became increasingly politically active. He took part in the Rajput alliance against Mughal Emperor Babur, fighting against the latter in the Battle of Khanwa alongside Rana Sanga of Mewar in the year 1527. Three of Raja Prithviraj's sons successively followed him as ruler of Amber, with many of his descendants also populating the kingdom's highest aristocracy in subsequent centuries.
