The Bishop of Annaghdown (or Annadown, Enachdune, Eanach Dúin) is an episcopal title which takes its name after the small village of Annaghdown in County Galway, Republic of Ireland.
The bishop was originally the ordinary of the diocese of Annaghdown, which was established in the 12th century.
[1] The cathedral had a dean, chapter and four vicars choral.
[2] Between 1253 and 1306, the bishopric was united to the archbishopric of Tuam, although in this period there were two bishops.
[3] In 1970, the Roman Catholic Church revived the title as the Titular Bishop of Eanach Dúin.
