Bhim Singh (? – 22 July 1537) was a sixteenth-century Rajput ruler of Amber. He was the eldest son of his father, Raja Prithviraj Singh I, by his wife Bala Bai, a daughter of Rao Lunkaran of Bikaner. Some sources allege that Prithviraj died at the hands of Bhim, who in turn was later killed by his own son Askaran. However, these claims of patricide are dismissed by historian Jadunath Sarkar, who asserts that they lack credibility since their sources are anonymous and undated. Bhim is also said to have overthrown his predecessor, his brother Puranmal, though this too is uncertain.
