Results by Constituency

Elections to the Parliament of Northern Ireland were held on the same day. 52 members were returned from ten constituencies, all of which were contested. The only Sinn Féin candidate who was elected to the Northern Ireland Parliament without also being elected to a constituency in the 26 counties was Seán O'Mahony (Fermanagh and Tyrone), although he was admitted as a member of the 2nd Dáil.

None of the Sinn Féin candidates elected in the six counties took their seats in the Northern Ireland Parliament. Apart from Seán O'Mahony, they were Michael Collins (Armagh), Eamon de Valera (Down), Arthur Griffith and Seán Milroy (Fermanagh and Tyrone) and Eoin MacNeill (Londonderry).
