The M1 is a motorway in Northern Ireland. It is the longest motorway in Northern Ireland and runs for 38 miles (61 km) from Belfast to Dungannon through County Down and County Armagh. It forms part of the route via the A1 in Northern Ireland (N1/M1 in the Republic of Ireland) between Belfast and Dublin as well as being a part of the unsigned European E01 and E18 routes.

The road begins at the Broadway roundabout to the west of Windsor Park and running parallel to the Blackstaff River. Heading south as a dual three–lane motorway, it passes to the east of Casement Park before crossing the Belfast-to-Newry railway line. Running through Dunmurry and Ballyskeagh it arrives to the south of Lisburn. Traffic for Dublin leaves at junctions 7 and 8 as the motorway enters the countryside. Now heading west past Aghnatrisk it runs parallel to and then crosses the Belfast-to-Newry railway line followed by the River Lagan before reaching Moira. Continuing west, it passes between Killaghy and Tullydagan and to the north of Lurgan and Turmoyra, across the Pound River, south of Lough Neagh, before its junction with the M12. Crossing the River Bann it then enters a relatively unpopulated area. It passes south of Derryadd Lough and runs in a loop around the Annagarriff Nature Reserve before crossing the River Blackwater, skirting to the north of Tamnamore and Laghey Corner before ending at Dungannon on the A4.
