Ringsend (Irish: An Rinn) is a southside inner suburb of Dublin, Ireland. It is located on the south bank of the River Liffey and east of the River Dodder, about two kilometres east of the city centre. It is the southern terminus of the East Link Toll Bridge. Areas included in Ringsend are the south side of the Dublin Docklands, and at the west end is the area of South Lotts and part of the Grand Canal Dock area. Neighbouring areas include Irishtown, Sandymount and the Beggars Bush part of Ballsbridge to the south, and the city centre to the west. A key feature of the area is the chimneys of Poolbeg power station.
Formerly the point where ships arriving from across the Irish Sea would dock, Ringsend went into decline in the 19th and 20th centuries, when the shipping moved to other locations, although there is still some container shipping.
