Phibsborough, also spelled Phibsboro,is a mixed commercial and residential neighbourhood in Dublin, Ireland. The Bradogue River crosses the area in culvert and the Royal Canal at Cross Guns Bridge. Formerly, a branch of the canal ran to the Broadstone basin, later the site of the Midland Great Western Railway Terminus and currently the headquarters of Bus Éireann. Mountjoy Prison is located in the district.

Phibsborough and Broadstone both have stops on the Luas Green Line located along the former Midland & Great Western Railway line.

The Phibsboro stop is located at the railway cutting between the North Circular Road and the Cabra Road. It has lateral platforms. Access to the platform level is from both the North Circular and Cabra Roads via stairs and lifts from the new deck levels abutting the existing road overbridges.

The Broadstone stop is located at Prebend Street and the Western Way. The Phibsboro stop serves the residential communities and facilitates interchange with bus services on the North Circular and Cabra Roads. The Broadstone stop serves the Mountjoy area and the newly built Dublin Institute of Technology campus located at Grangegorman.

The Luas Cross City project has joined the Luas Red and Green lines with a line from Broombridge in North Dublin (interchange with Irish Rail station) and St.Stephen's Green Green Line stop. Services began in December 2017.
