Thornport is a census-designated place in Perry County, in the U.S. state of Ohio.

Thornport is an unincorporated village laid out by Dr. W. W. Talbott in 1839, when his private improvement company dug a private feeder canal to connect Thorn Township to the main body of Licking Summit Reservoir in Fairfield and Licking counties.

But after a mid-century storm, all fell to ruin, until a nearby railroad stabilized the pioneer village with traffic and visitors.

At least one log cabin remains in Thornport, a testament to its early pioneer days and the canal trade.

Nearby is the village of Thornville, established later and with numerous homes of the Victorian era.
