Michael Geoffrey St Aubyn Jackson (born 24 May 1956) is a Church of Ireland Anglican bishop.

[citation needed] In 1976,[1] as only a Junior Freshman, he was elected as a scholar of the college in classics, the greatest undergraduate achievement.

Jackson also plays an active role in the wider Anglican Communion, especially in the areas of ecumenism and inter-faith dialogue.

[3][4] Jackson has caused several controversies during his incumbency in Dublin, including a media fracas regarding comments about sectarianism made in a speech during the 2013 diocesan synod[5] There was also controversy over the closure of the 200 year old Church of Ireland College of Education and its amalgamation into Dublin City University, ending the historic link with Trinity College, Dublin[6] Jackson declined to make a statement either in favor of or against the 2024 referendums on the family and care, citing the level of debate around the term "durable".

[7] Ultimately, both proposals were rejected by the voters, leading Leo Varadkar to decide to step down as Taoiseach; while some media outlets linked this decision to the failure of both referendums, the Green Party leader, Eamon Ryan said he did not believe it was the "defining reason" for the resignation.
