Tallaght (/ˈtælə/ TAL-ə; Irish: Tamhlacht, IPA: [ˈt̪ˠəul̪ˠəxt̪ˠ]) is the largest town, and county town, of South Dublin, and the largest suburb of the city of Dublin, Ireland. The village area, dating from at least the 1st century, held one of the earliest settlements known in the southern part of the island, and one of medieval Ireland’s more important monastic centres.[2]

Up to the 1960s Tallaght was a small village in County Dublin, linked to several nearby rural areas which were part of the large civil parish of the same name – the local council estimates the then population at 2,500.[3] Suburban development began in the 1970s and a town centre area has been developing since the late 1980s. There is no legal definition of the boundaries of Tallaght, but the electoral divisions known as “Tallaght” followed by the name of a locality have, according to the 2016 census, a population of 76,119,[1] up from 69,454 over five years.[4][5] There have been calls in recent years for Tallaght to be declared a city.[6]
