Who We Are

The Story of Friends of Sinn Féin USA


The story of Friends of Sinn Féin USA is the story of the peace process, the signing of the Good Friday Agreement, prisoner releases, policing reform, opposing Brexit and promoting Irish Unity. With your support Sinn Féin leads government in the North and is the largest party across all Ireland.  There is more to be done to protect this progress, to implement agreements and to build a new and united Ireland.

Established in 1994 following the first visit to the USA by Gerry Adams, then President of Sinn Féin, we are proud to support the  work of Sinn Fein in Ireland and the USA. Friends of Sinn Féin USA is the authorised and official body to support Sinn Fein in the USA. FoSF is not a membership run organisation. Additional information is on file with the Department of Justice, Washington, DC. 

"You could be the Irish American who comes home to a free, united, peaceful and prosperous Ireland"

~ Gerry Adams

What We Do

The USA has and remains central to the cause of Irish unity, independence, and freedom. From Wolfe Tone, to the Fenian movements, the 1916 Rising, the 1981 Hunger Strikes, the peace process and Good Friday, America has been central.

Friends of Sinn Féin support Sinn Féin Leaders to visit, to inform and encourage the USA to continue to support peace, the Good Friday Agreement and Irish Unity.

Donations to Friends of Sinn Féin directly support the work of Sinn Féin in North of Ireland and to maintain our work in the USA.

American support is crucial to building a new and united Ireland.

About Sinn Féin

Sinn Féin is an Irish political party founded in 1902 at a time of a growing desire for freedom. The three great  movements of the time, the National Movement, the Women's Movement and the Labor Movement, were coming together in the common cause of Irish independence.

It was a time of revolution and change in Ireland which would later be spelt out in the words of the 1916 proclamation and in the democratic program of the First Dáil Éireann.

Sinn Féin is an Irish republican party. We stand for Irish re-unification, an end to the partition of our country. Sinn Féin is the only party working to achieve Irish unity. 

Sinn Féin led the Irish Peace Process which ended 30 years of conflict and was central to the negotiation of the Good Friday Agreement.

With your support, Sinn Féin is again the largest political party in Ireland.
