Comhairle na Poblachta (Irish for 'Council of the Republic') was an Irish republican organisation established in 1929.

The organisation had the support of the IRA, which had agreed to its formation at its General Army Convention in January 1929. An early Saor Éire programme had also been proposed, but was rejected in favour of Comhairle na Poblachta. and its membership was drawn from Sinn Féin, Fianna Éireann, the IRA, Cumann na mBan and left-wing republicans.

During the Army Convention in February 1931, the increased ranks of left-wing republicans led by Peadar O'Donnell approved a re-drafted Saor Éire programme.
