Rory O'More Bridge, Cast iron bridge in central Dublin, Ireland.

Rory O'More Bridge is a blue-painted cast-iron road bridge over the River Liffey in Dublin, joining Watling Street by the Guinness grounds to Ellis Street and the north quays. Its single arch spans 29 metres, carried by seven parallel cast-iron arch segments that support the deck's T-beams; the deck itself is wrought-iron plates covered with road surfacing, resting on granite abutments.

The structure was built in 1859 from cast iron, replacing an older stone bridge at the same location. Originally called Victoria & Albert Bridge when it opened, it received its current name during the 1930s.

The bridge carries the Irish name Droichead Ruaraí Uí Mhóra and honours Rory O'More (1600–1655), a leader of the 1641 plot to seize Dublin. Before that it was briefly called Emancipation Bridge, renamed in 1929 for the centenary of Catholic emancipation.

The bridge functions as a public crossing over the Liffey with direct access to both riverbanks in central Dublin. The well-maintained structure is accessible at all times and provides straightforward pedestrian passage between the surrounding neighborhoods.

Before 1859, a wooden bridge called Bloody Bridge stood at this location, named after violent clashes between local ferrymen and bridge builders. This earlier name recalls the fierce disputes that preceded the current structure.
