The M18 motorway is a motorway in Yorkshire, England. It runs north east from junction 32 of the M1 motorway just east of Sheffield, then passes east of Rotherham and Doncaster to finish at junction 35 of the M62 motorway, just west of Goole. It meets the A1 at junction 2 (A1 junction 35).

Much of the M18 is a two lane dual carriagway, and carries relatively low volumes of traffic. However, the section linking the M1 and A1 is much busier.

The M180 motorway leaves the M18 at junction 5.
