Iowaville was a small town on the lowland near the northeast bank of the Des Moines River, near the line between Davis and Van Buren counties, and between present-day Eldon and Selma, Iowa, United States.

Iowaville is now farm land with almost nothing to show the town location, but it is an important Iowa archaeological site.

The residents of Iowaville were frequent visitors to Fort Madison, 1808–1813, the first U.S. Army post in the Upper Mississippi.

[8] Trader and settler John Jordan operated near here from 1837[5] and platted the town in 1838.

[9][10] The town was prosperous for a time, with a peak population of perhaps 200, but it declined rapidly after the railroad came to nearby Eldon.
