The route of the A4 in orange from Portadown (County Armagh) to Belcoo (County Fermanagh). The Northern Irish M1 is in blue, and the N16 is in red.

The A4 is a major east–west road in Northern Ireland. It travels for 69.2 miles from Portadown to Belcoo through County Armagh, County Tyrone and County Fermanagh.

Although once being a single continuous route, the A4 nowadays is split into two completely divided stretches. The route branches off from the A3 Lisburn-Armagh road in Portadown and meets the M1 at Junction 12. The A4 the re-appears at the end of the M1 motorway at Junction 15 south of Moygashel, from which point it continues uninterrupted to the border village of Belcoo in western County Fermanagh. At the border with the Republic of Ireland, the A3 meets with the N16 road to Sligo. For its entire length the A4 is a primary route. At present, it is mainly single carriageway, apart from a 13 mile long section from the end of the M1 at Moygashel until Ballygawley, which is dual carriageway. There are numerous stretches of the route which have overtaking lanes through counties Tyrone and Fermanagh.
