Rosanna "Rosie" Hackett was an Irish revolutionary and trade union leader. She was a founder-member of the Irish Women Workers' Union, and supported strikers during the 1913 Dublin Lockout. She later became a member of the Irish Citizen Army and was involved in the 1916 Easter Rising. In the 1970s, the labour movement awarded Hackett a gold medal for decades of service, and in 2014 a Dublin city bridge was named in her memory.

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).
