Máire Devine (born 22 October 1972)[1][2] is an Irish Sinn Féin politician who has served as a Teachta Dála (TD) for Dublin South-Central since November 2024.

[3][4] Devine was born in The Liberties to a family of republicans involved in campaigns around the 1981 Irish hunger strike.

[8] Devine was co-opted onto South Dublin County Council in 2011, representing Tallaght Central.

[10] In 2018, she was suspended from Sinn Féin for three months after retweeting a parody Twitter account that referred to Irish Prison Service officer Brian Stack (fatally shot by the Provisional IRA in 1983) as a "sadist.

Later in the same year, she was added to Sinn Féin's ticket in Dublin South-Central alongside Aengus Ó Snodaigh and Daithí Doolan.
