Interstate 71 (I-71) is a north–south Interstate Highway in the midwestern and southeastern regions of the United States. Its southern terminus is at an interchange with I-64 and I-65 (the Kennedy Interchange) in Louisville, Kentucky, and its northern terminus at an interchange with I-90 in Cleveland, Ohio. I-71 runs concurrently with I-75 from a point about 20 miles (32 km) south of Cincinnati, Ohio, into Downtown Cincinnati. While most odd numbered Interstates run north–south, I-71 takes more of a northeast–southwest course, with some east–west sections, and is mainly a regional route serving Kentucky and Ohio. It links I-80 and I-90 to I-70 and ultimately (via I-65) links to I-40. Major metropolitan areas served by I-71 include Louisville, Cincinnati, Columbus, and Cleveland.

Approximately three-quarters of the route lie east of I-75, leaving I-71 out of place in the Interstate grid.
