Horton is an unincorporated community in Polk Township in Bremer County, Iowa, United States.

Horton lies at the junction of Iowa Highway 188 and County Road V14.

The Horton post office was established in 1857, and a schoolhouse, the first frame schoolhouse in Polk Township, was built in 1859.

These buildings were soon joined by a store, a blacksmith shop, and houses.

[4] Horton's population had increased to 100 in 1925,[5] but the town's fortunes began to decline after that.
