Dhan Singh Gurjar, also known as Dhunna Singh, was the Indian kotwal (police chief) of Meerut, who participated in the 1857 uprising and led initial actions against the British East India Company in Meerut. Dhan Singh and several other policemen later deserted the police force (kotwali). He is believed to have led thousands of villagers from all across the Meerut district to the city's jail. According to the official records, the rebels released 839 prisoners from the jail. These prisoners were among the rebels who participated in the Siege of Delhi.
