Harry Boland was an Irish republican politician who served as President of the Irish Republican Brotherhood from 1919 to 1920. He served as a Teachta Dála from 1918 to 1922.
He was elected at the 1918 general election as the MP for South Roscommon, but as with other Sinn Féin candidates, he did not take seat in the British House of Commons, serving instead as a TD in the First Dáil.
At the 1921 general election, Boland was elected to the second Dáil as one of the TDs for the Mayo South–Roscommon South. He was re-elected in 1922 as an Anti-Treaty candidate, but died two months later in the Irish Civil War.
