James (Séamus) Devins (1873 – 20 September 1922) was an Irish Sinn Féin politician. He was elected unopposed as a Sinn Féin Teachta Dála (TD) to the 2nd Dáil at the 1921 elections for the Sligo–Mayo East constituency.He opposed the Anglo-Irish Treaty and voted against it. He was re-elected as an anti-Treaty Sinn Féin TD to the 3rd Dáil at the 1922 general election. His death in September 1922 "at the hands of former comrades" would indicate that he was a casualty of the Irish Civil War.
