Taney is a populous parish in the Church of Ireland, located in the Dundrum area of Dublin.
Taney's origins go back to the early Irish saint Nathi, who in the 6th century established a centre for monastic life. This centre may have been on what is now the site of St. Nahi's Church in Dundrum. The derivation of the parish name, Taney, suggests that it derives from the Irish Teach Nahi or Nahi's house. Another possible source is Tamhnach, meaning a green field or arable spot. While there are no details available, there seems little doubt that religious worship was taking place here for some considerable time before the Anglo-Norman Invasion of 1169-1171, which made use of a Papal Bull asserting Rome's rights to all islands off the coast of Europe. The Rural See (seat of a Rural Bishop) of Taney is mentioned in a report of Cardinal Paparo in 1152. The next record is as "the Deanery of Tanhy" in a taxation list sent from Rome to the Diocese of Dublin.
When Henry II granted Leinster to Strongbow, Tacheny was one of two areas held back, being allocated to Hugh de Clahull, who later passed his Dublin lands to the Archbishop of Dublin. In a Papal Bull of 1179, there is a reference to "the middle place of Tighney" (annotated in the Liber Niger of a later Archbishop, Alen, as "alias Tawney"), with a church and three subsidiary chapels (at Donnybrook, Kilgobbin and Rathfarnham).
In 1235, the Rural Dean of Taney was J. Matthew. Archbishop Luke (1228–1255) established Taney as a prebend of St. Patrick's Cathedral and until 1851, the Archdeacons of Dublin held the Prebendary and the post of Rector of Taney, and the parish was chiefly overseen by curates-in-charge.
