Calhoun is a home rule-class city in McLean County, Kentucky, United States.

Present-day Calhoun was first known as "Rhoadsville" after the German-born Pennsylvanian Captain Henry Rhoads (1739–1809), who laid out the town from 1784 to 1785 near the Long Falls of the Green River.

His brother Solomon then erected a fort to protect the settlers and the transit around the falls.

[4][5] At some later point, presumably out of confusion with the more famous Senator and Vice President John Calhoun of South Carolina, the spelling of the town was changed.

In 1854, it beat out the settlement of Rumsey on the other side of the river to become the seat of the newly formed McLean County.

Kentucky Route 256 leaves the center of Calhoun as 1st Street and leads northwest 10 miles (16 km) to Beech Grove.

Kentucky Route 136 crosses the northern end of Calhoun, leading northwest to Beech Grove as well and southeast 10 miles (16 km) to Livermore.
