Ormeau, a division of Belfast, was a UK parliamentary constituency in Ireland.
It returned one Member of Parliament (MP) to the House of Commons of the United Kingdom from 1918 to 1922, using the first past the post electoral system.
This was evident in the very low performance by Sinn Féin in the 1918 election.
After the 1918 election, Sinn Féin invited all those elected for constituencies in Ireland to sit as TDs in Dáil Éireann rather than in the House of Commons of the United Kingdom.
