Ratan Singh was the ruling Maharaja of the princely state of Bharatpur from 1768 to 1769.
He ascended the throne after the death of Maharaja Jawahar Singh.[1] Jawahar Singh had no son, hence he was succeeded by his brother, Ratan Singh. During a Holi festival held in Vrindavan, a possibly drunk Ratan Singh was killed by a dwarf in Bharatpur where a very dilapidated "Ratan Chhatri" is still present. His son Maharaja Kehri Singh succeeded him in 1769.
