Tullaherin (Irish: An Tulaigh Thirim) is a civil parish and townland in County Kilkenny, Ireland.

[1] Tullaherin townland is the site of a number of historical archeological remains, including a round tower, an 11th-13th century ruined church and two ogham stones.

Most probably it was after this date that the top was rebuilt on the same principle as Clonmacnoise with eight windows instead of the usual four.

[3][note 1] The Tullaherin Folk Museum can be viewed at the old parochial residence.
