Die Sankt-Brendan-Kathedrale von Annaghdown (irisch Ardeaglais Eanach Dhúin, englisch Annaghdown Cathedral of St. Brendan) war eine Brendan dem Reisenden gewidmete Bischofskirche des Bistums Eanach Dhúin am Lough Corrib im heutigen County Galway in Irland, das im 12. Jahrhundert gegründet wurde und jahrhundertelang in einer Auseinandersetzung mit der Erzdiözese Tuam um Anerkennung rang. Nach der Reformation im 16. Jahrhundert fiel die Kirche an die Church of Ireland, die die Kirche baulich veränderte und bis mindestens in das 18. Jahrhundert als Gemeindekirche nutzte.
