The area where St. Paris now stands was originally inhabited by Native Americans.

The first white settlers arrived in 1797 and the village was founded in Johnson Township[5] in 1831 by David Huffman, who originally named it New Paris, after the French capital city of Paris.

[6] In 1846 and 1847 the Columbus and Piqua Railroad was built along the southern boundary of the village, greatly increasing its advantages compared to other communities in the surrounding area.

[6] After reorganization, when the Columbus, Piqua and Indiana Railroad between Columbus, Ohio, and Union City, Indiana opened on March 25, 1859, the local station was the most efficient transport option for area agricultural products and travellers.
