Abhartach (pronounced [ˈəuɾˠt̪ˠəx]; Irish for 'dwarf'), also Avartagh, is an early Irish legend, which was first collected in Patrick Weston Joyce's The Origin and History of Irish Names of Places (1870). Abhartach should not be confused with the similarly named Abartach, a figure associated with Fionn mac Cumhaill.
