Pottinger, 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.
[citation needed] The constituency was a strongly unionist area, with some Labour support.
Sinn Féin demonstrated republican weakness in the seat by receiving only 393 votes, 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.
