The M42 motorway is a major road in England. The motorway runs north east from Bromsgrove in Worcestershire to just south west of Ashby-de-la-Zouch in Leicestershire, passing Redditch, Solihull, the National Exhibition Centre and Tamworth on the way.

Along with sections of the M5 and M6 motorways, the southern sections of the M42 form an orbital motorway around Birmingham.
