Arthur Joseph Griffith (31 March 1871 – 12 August 1922) was an Irish writer, newspaper editor and politician who founded the political party Sinn Féin.

He led the Irish delegation at the negotiations that produced the 1921 Anglo-Irish Treaty, and served as the president of Dáil Éireann from January 1922 until his death later in August.

Arthur Joseph Griffith was born at 61 Upper Dominick Street, Dublin on 31 March 1871, of distant Welsh lineage. His great-great-grandfather, William Griffith of Drws-y-coed Uchaf, Rhyd-ddu, Caernarvonshire (1719-1782), was a farmer and supporter of the Moravian Church cause. His great grandfather, Griffith Griffith (b. 1789), emigrated first to the United States and then to Ireland, where some of his sisters had settled in Dublin among the Moravian community there. A Roman Catholic, Griffith was educated by the Irish Christian Brothers. He worked for a time as a printer before joining the Gaelic League, which was aimed at promoting the restoration of the Irish language.
