The A180 is a primary route in northern England, that runs from the M180 motorway to Cleethorpes. The road is a continuation of the M180, but built to lower specifications: it is mainly dual two-lane without hard shoulders. The road is (mostly grade separated) dual carriageway for 15 miles (24 km) from the M180 to Grimsby, and is a single carriageway road for 2 miles (3.2 km) between Grimsby and central Cleethorpes. The road forms part of the unsigned Euroroute E22.

The A180 begins at junction 5 of the M180 in North Lincolnshire, where it picks up traffic from the motorway and the A15 road heading towards the ports of Grimsby and Immingham. The road crosses the border into North East Lincolnshire and has a junction with the A160 road to Immingham Dock. It bypasses the town of Immingham and Habrough before meeting the A1173 road (linking to the A46 road to Lincoln). The road then has a junction with the A1136 road prior to having two roundabout junctions with local roads. In central Grimsby, the A180 meets the A16 road (to Louth and Boston) at a roundabout, and continues along the front into Cleethorpes. In central Cleethopes the A180 terminates at a roundabout with the A1098 road.
The A180 was opened in 1983 as an extension to the M180.
Its ribbed concrete surface makes it the noisiest road in the United Kingdom. In the 2000s, parts of the road that lie close to inhabited areas were resurfaced with tarmac following continued complaints and campaigns. Calls for the entire stretch of the road to be resurfaced continue to the present day.
