The M70 motorway () is a motorway in Hungary, connecting the M7 motorway to the A5 motorway in Slovenia. The road is 21 km long and has a speed limit of 130 km/h. The last section was completed in 2006. After the opening of the last missing sections of the M7 on August 19, 2008, there is a direct motorway link from Budapest to Slovenia. The expressway originally consisted of two lanes between Letenye and Tornyiszentmiklós interchanges. As a four-lane, full profile motorway, it opened on December 13, 2019 (see the Hungarian article for references in Hungarian). It was built by the Colas Group.
