The Rosie Hackett Bridge is a road and tram bridge in Dublin, Ireland, which opened on 20 May 2014. Spanning the River Liffey and joining Marlborough Street to Hawkins Street, it is used solely by public transport, taxis, cyclists and pedestrians. It is 26 metres wide and 48 metres long, and is a single span, smooth concrete structure, with the underside of the bridge designed to be as high above the water as possible so that river traffic is not impeded. It was built to carry the extended Luas Green line, and was budgeted at €15 million. It is named for trade unionist Rosie Hackett (1893–1976).

The River Liffey is a river in eastern Ireland that ultimately flows through the centre of Dublin to its mouth within Dublin Bay. Its major tributaries include the River Dodder, the River Poddle and the River Camac. The river supplies much of Dublin's water and supports a range of recreational activities.
