Ringsend is a suburb of Dublin, the capital of Ireland. It is located directly on the south side of the River Liffey, about two miles to the east of the city centre.

Formerly the point where ships arriving across the Irish Sea would dock, it went into decline in the 19th and 20th centuries when the shipping moved to ports further south along the coast.

With the growth of Dublin in the "Celtic Tiger" years of the 1990s and later, Ringsend has become a popular spot for students and younger workers, looking for an area close to the city's night-life, but which also has access to parks and the sea. The first years of the 21st century has seen significant growth in the area, with the adjoining Grand Canal Docks Project and U2 Tower due for completion in 2008/2009.

Ringsend was originally a long narrow peninsula separated from the rest of Dublin by the estuary of the Dodder river. Since the Irish for peninsula is Rinn, pronounced 'Ring', it seems likely that the name means 'the end of the peninsula'.
