"Dadri" is derived from a lake called "Dadar" which was full of "dadur" (Sanskrit: frog) from which it took its current name. To distinguish Dadri from other similarly named places in the area, sometimes Dadri's name was appended to the nearby village of "Charkhi". After India became independent, in recognition of the contribution of people of Charki village during the first war of independence in 1857 against the British colonial rule and Praja Mandala movement against the oppressive rule of the Jind State, the government officially named the town as "Charkhi-Dadri".
