Ruth Coppinger, Irish politician and member of the Socialist Party, and Teachta Dála (TD) for the Dublin West constituency, is born in Dublin on April 18, 1967.

Coppinger is a member of Fingal County Council for the Mulhuddart local electoral area from 2003 to 2014. She is co-opted to the council in 2003, replacing Joe Higgins, and is elected in 2004 and re-elected in 2009. She is an unsuccessful candidate for the Socialist Party at the 2011 Dublin West by-election.

Following victory in the 2014 Dublin West by-election, Coppinger joins her party colleague Joe Higgins in the Dáil. After being elected, she calls for a mass campaign of opposition to water charges being implemented by the Fine Gael–Labour Party coalition.

In November 2014, Coppinger calls for the gradual nationalisation of U.S. multinationals to prevent job losses. In response, Fianna Fáil’s jobs spokesperson Dara Calleary calls the idea “reckless and ludicrous,” as it would “place a massive burden on taxpayers and the public finances.”

In September 2015, Coppinger joins homeless families from Blanchardstown, in occupying a NAMA-controlled property as part of a campaign to raise awareness of the housing crisis. In October 2015, she joins families in their occupation of a show house in her constituency, to protest the lack of availability of affordable social housing. She also supports the tenants of Tyrrelstown, who are made homeless when a Goldman Sachs vulture fund sells their houses.

Coppinger is re-elected to the Dáil at the 2016 Irish general election, this time under the Anti-Austerity Alliance–People Before Profit banner. On March 10. 2016, at the first sitting of the 32nd Dáil, she nominates Richard Boyd Barrett for the office of Taoiseach, quoting James Connolly from a hundred years previously when she says, “The day has passed for patching up the capitalist system. It must go,” and declaring, “We will not vote for the identical twin candidates” of Fine Gael and Fianna Fáil after they “imposed austerity.” On April 6, 2016, following the failure of the Dáil to elect a Taoiseach at that first sitting, she is nominated for the role of Taoiseach, becoming the first female nominee in the history of the state.

In 2018 Coppinger praises the MeToo movement for exposing patterns of abuse and systemic inequality. However, she also notes the limitations of achieving justice through traditional channels and calls for a stronger focus on combating intimate partner violence and societal tolerance of such abuse.

In April 2018, in the lead-up to the repeal of the Eighth Amendment, Coppinger, along with her colleague Paul Murphy, holds up a Repeal sign during leader’s questions and is reprimanded by the Ceann Comhairle. She is an advocate for abortion rights in Ireland, and is a founding member of ROSA, a movement for reproductive justice in Ireland. Earlier, in 2016, she tables the private members’ motion to repeal the Eighth Amendment.

In November 2018, Coppinger protests in the Dáil against the conduct of a rape trial in Ireland. During the trial, the defence team, as part of their argument that the sex had been consensual, states that the 17-year-old victim had worn a thong with a lace front. The defendant is subsequently found not guilty. During a sitting of the Dáil, Coppinger holds up a similar pair of underwear and admonishes the conduct of the trial, suggesting victim blaming tactics had been used and suggests this is a routine occurrence in Irish courts. She calls on Taoiseach Leo Varadkar to support her party’s bill that would increase sex education in Irish schools and provide additional training to the Irish judiciary and jurors on how to handle cases of rape. Varadkar responds that victims should not be blamed for what happens to them, irrespective of how they are dressed, where they are or if they have consumed alcohol.

In 2019 Coppinger sponsors a private member’s bill – the Domestic Violence (No-contact order) (Amendment) Bill 2019. The bill lapses with the dissolution of the Dáil and Seanad.

At the general election in February 2020, Coppinger is defeated in the Dublin West constituency. She unsuccessfully contests the 2020 Seanad election for the National University of Ireland constituency.

In June 2024, Coppinger is elected to Fingal County Council for the Castleknock local electoral area on the 7th Count. At the 2024 Irish general election, she is re-elected to the Dáil.

Coppinger is an advocate of secularism and believes in abolishing both the Angelus and the Dáil prayer, viewing them as relics of an outdated intertwining of religion and governance. She supports the separation of Church and State, criticising the Catholic Church‘s historical influence in education and health, as well as its financial privileges, including exemptions from accountability under regulations like SIPO. She has called for the requisitioning of Church lands and property, citing the Church’s failure to meet commitments to abuse victims and the necessity of addressing historical injustices.

On drug policy, Coppinger supports decriminalisation and endorses the Portuguese model, which treats addiction as a health issue rather than a criminal matter. She emphasises the hypocrisy of criminalising drug use while overlooking the societal harm caused by alcohol and advocates for expanding access to medicinal cannabis, criticising the political inertia in addressing this need.

In 2013, during referendum to abolish the Irish senate, Coppinger campaigns for a yes vote, calling the institution elitist and undemocratic. However, in 2020, following the loss of her Dáil seat, she runs unsuccessfully for a seat in the Senate. Challenged by the Irish Examiner on this, she states that so long as the Senate continues to exist, it should be used to further progressive causes.

Coppinger lives in Mulhuddart and is a secondary school teacher. Her eldest brother, Eugene Coppinger, serves on Fingal County Council from 2011 to 2019.
