爱尔兰教会，或称爱尔兰圣公会，是普世圣公宗团契的一员，普世圣公宗两个母会之一（另一个是英格兰教会)。在普世圣公宗各成员教会中列位第二，在英格兰教会之后。它有12个教区组成。

目前，爱尔兰首都都柏林有2个圣公会大教堂：圣派屈克大教堂和基督堂座堂，并且拥有全爱尔兰所有仍然在使用的中世纪教堂教产。圣公会运营的爱尔兰圣公会神学院位于都柏林南郊，与都柏林三一学院的神学院合办，是都柏林大学的一个部分。都柏林大学与牛津大学和剑桥大学成为一个系统，合称为牛剑都柏林，构成英伦古典大学的圣公会部分。教会的中央事务所位于Rathmines，毗邻爱尔兰圣公会教育学院。1999年，教会投票决定禁止使用除圣帕特里克旗以外的其它旗帜，然而联合旗继续在北爱尔兰的很多教堂使用。

The Church of Ireland (Irish:Eaglais na hÉireann Scots:Kirk o Airlann) is a Christian church in Ireland and an autonomous province of the Anglican Communion. It is organised on an all-Ireland basis and is the second-largest Christian church on the island after the Catholic Church. Like other Anglican churches, it has retained elements of pre-Reformation practice, notably its episcopal polity, while rejecting the primacy of the Bishop of Rome. Nevertheless, in theological and liturgical matters, it incorporates many principles of the Reformation, particularly those espoused during the English Reformation. The church self identifies as being both Catholic and Reformed. Within the church, differences exist between those members who are more Catholic-leaning (high church) and those who are more Protestant-leaning (low church or evangelical). For historical and cultural reasons, the Church of Ireland is generally identified as a Protestant church. The Church of Ireland is the second-largest in the Republic of Ireland, with around 130,000 members, and the third-largest in Northern Ireland, with around 260,000 members.
