Katni is a town on the banks of the Katni River in Madhya Pradesh, India. It is the administrative headquarters of Katni District. It is in the Mahakoshal Region of Central India.

It also has the Ordnance Factory Katni of the Ordnance Factories Board which manufactures products for the Indian Armed Forces.

Katni is a conglomeration of culture from three cultural states — Mahakausal, Bundelkhand, and Baghelkhand. There are three stories which may explain why Katni is called Mudwara.

Katni junction has a half circular Mode (turn) from the wagon yard. So people call it “Mudwara”.

Another story is that there was a village called Modwar that was given as a reward for the bravery of cutting Mud (heads).

A similar story is that the British government used to cut the heads of baggies and plunderers, and hang them in squares to instill fear in the population and deter them from criminal activity.

One of the prime junctions of Indian railways, Katni Junction is in the heart of the rail network. Trains come to Katni from five directions (Bina, Jabalpur, Satna, Bilaspur, Singrauli), as it is at the junction of trunk rail routes connecting north-south and east-west. The public has access to almost all parts of the country directly through mail express trains from Katni. The railways are now establishing a new zone at Jabalpur.

Dussehra is the biggest annual festival in Katni district. The effigy of Ravana made here ranges in height from 43 to 49 metres (141–161 ft) in Kymore every year. People from far away visit to witness the event. Burning of the effigy was temporarily discontinued due to safety reasons and has resumed.
