Dublin and the Belfast Junction Railway (D&BJct) was an Irish gauge (5 ft 3 in (1,600 mm)) railway in Ireland. The company was incorporated in 1845 and opened its line in stages between 1849 and 1853, with the final bridge over the River Boyne opening in 1855. It linked the Ulster Railway (UR) from Belfast to Portadown and Dublin and Drogheda Railway (D&D) from Drogheda to Dublin, completing the missing link in the Belfast–Dublin line.

The Boyne Viaduct at Drogheda was not built until 1854–55, at a cost of £124,000, to the design of Sir John Macneill, who was the consulting engineer for the D&BJct.

The D&BJct line from Drogheda to Portadown connected the Ulster Railway's Armagh – Portadown – Belfast Great Victoria Street original line with the Dublin and Drogheda Railway's Dublin Amiens Street – Drogheda line, forming the main line between Dublin and Belfast.

In 1875, the D&BJct merged with the Dublin and Drogheda Railway (D&D), forming the Northern Railway of Ireland. This was in turn one of the companies that amalgamated to form the Great Northern Railway of Ireland in 1876.
