Interstate 180 (I-180) is a one-mile (2 km)-long connector in the U.S. state of Wyoming between Interstate 80 and downtown Cheyenne, Wyoming.

It is unusual for being one of the few Interstate highways that does not follow Interstate highway standards. There is also no freeway anywhere along its route. It is a divided highway with a 40 mph (64 km/h) speed limit due to the frequency of signals.

There are Business US 30 shields where W Lincolnway splits off from I-80 (Photos: , from ) and on E Lincolnway (Photos: , from ) but there are East US 30/West US 30 shields at other places, including the I-180 junction.
