The Dhala impact structure (N25°17'59.7" and E78°8'3.1") is an impact structure formed by an asteroid impact.^[1] It is situated near Bhonti village in Pichhore block of Shivpuri district of Madhya Pradesh state in India.^[2] It is the largest impact structure in India,^[2] and between the Mediterranean and Southeast Asia. The diameter of the structure is estimated at 3 kilometres (1.9 mi),^[3] while other sources estimate its diameter to be 11 km diameter. It is the second such structure found in India, after Lonar lake.^[2]

It is 200 km east of the Ramgarh crater.

It is estimated that the impact occurred between 2.44 and 2.24 Ga.^[4] Basement rocks are predominantly composed of granitoids.

This impact structure on the Bundelkhand craton is the largest in India.^[2][5]
