Westmoreland Street is a street in the southern city-centre of Dublin, Ireland. It is currently a one-way street and part a north-bound section of the R138 road.
It is one of the two broad avenues - along with D'Olier Street - that converge at their northern ends at O'Connell Bridge over the River Liffey. Westmoreland Street links the bridge to Trinity College at College Green at its southern end, from where traffic diverges between Grafton Street to the south and Dame Street to the west. Westmoreland Street also constitutes the eastern border of Temple Bar.
Westmoreland street has a stop on the Luas Cross City line (northbound only). This line links the Red and Green lines and runs from Broombridge in North Dublin and St.Stephen's Green. Construction started in June 2013.
