Ratanpur is a town and a nagar palika in Bilaspur district in the Indian state of Chhattisgarh.

According to the 1114 CE Ratanpur inscription of the local king Jajjaladeva I, his ancestor Kalingaraja conquered Dakshina Kosala region, and made Tummana (modern Tuman) his capital.

Senasahibsubha Raghuji Bhonsle's son Bimbaji ruled over Chhatisgarh from his capital in Ratanpur.

The Central Provinces covered part of Chhattisgarh and Maharashtra states and its capital was Nagpur.

The town is popular as a religious center and many Hindu devotees come here to offer their prayers and seek the blessings at the Mahamaya Temple, goddess Mahamaya also known as Kosaleswari, as she was presiding deity of Dakshin Kosal (modern Chhattisgarh).
