National Basketball Arena, also known as Tallaght Arena, is an indoor sporting arena located in Tymon Park, Tallaght, South Dublin, adjacent to the M50 motorway. The capacity of the arena is 2,500 people and it opened in January 1993. It is used mainly for basketball events, but has also hosted other indoor sports, most notably futsal, as well as exhibitions, concerts and cultural events.

Tallaght is the largest settlement, and county town, of South Dublin, Ireland, and the largest satellite town of Dublin. The central village area was the site of a monastic settlement from at least the 8th century, which became one of medieval Ireland's more important monastic centres.
