Tonk is one of the well-renowned districts of Rajasthan. The city of Tonk is the administrative headquarters of the district. It is situated near the right bank of Banas, just 60 miles by road south from Jaipur. Tonk was also the capital of the eponymous princely state of British India from 1817 to 1947. Tonk has been called ‘Rajasthan ka Lucknow’, ‘Adab ka Gulshan’, ‘Romantic poet Akhtar Shreerani ki Nagri’, ‘Meethe Kharboojo ka Chaman’, and ‘Hindu Muslim Ekta ka Maskan’ . These names designate Tonk a significant status in Rajasthan.

It is bounded on the north by Jaipur district, in the east by Swai Madhopur district and in the west by Ajmer district. The total geographical area of Tonk district is 7.16 lac hectares, but for land utilization purpose the area is reported to be 7.19 lac hectares in the year 2002-03 as per land record papers.

Tonk district forms the shape of kite or rhombus with its eastern and western sides bending somewhat inward and the south-eastern portion protruding between Sawai Madhopur and Bundi districts. The district is flat at a general elevation of about 214.32 meters above sea level with rocky but scrubby hills. The soils are fertile but somewhat sandy and the subsoil water is limited. The distinguishing feature of Tonk district is the Aravali system, which starts from Bhilwara district and running along the boundaries of Bhilwara and Bundi districts, enters Tonk district in the south near Rajkot and continues in a north eastern direction until it leaves the district near Banetha.
The Bisalpur dam is situated 17 Kms. from Deoli. The water storage capacity of this dam is 315.50 meter. Apart from providing water to Jaipur, Ajmer, Nasirabad, Beawar, Kishangarh etc., this dam provides irrigation facilities to Deoli, Tonk & Uniara tehsils. Due to this dam, subsoil water level has risen in Deoli, Tonk, Malpura and Todaraisingh which resulted in increasing the fertility of soil and yield of crops.
