Dominic Hannigan (born 1 July 1965) is an Irish former Labour Party politician who served as a Teachta Dála (TD) for the Meath East constituency from 2011 to 2016.

[9] In Seanad Éireann he was the Labour Party Whip and spokesperson on Commuter Issues, Environment and Local Government, Foreign Affairs and Defence.

He was one of the first members of the Oireachtas to support the candidacy of Eamon Gilmore, following the resignation of Pat Rabbitte as leader of the Labour Party on 23 August 2007.

In September 2007 he submitted proposals to the Department of Environment and Local Government for town councils for Ashbourne and the Meath coastal area, and called for the abolition of county managers.

[10] Hannigan said in 2011 that population growth during the Celtic Tiger years was more dramatic in Meath than elsewhere in Ireland and that this was having a profound effect on the county's education system.
