West Down was a UK Parliament constituency in Ireland which returned one Member of Parliament from 1885 to 1922, using the first past the post electoral system.

This county constituency was first created in 1885 from the western part of Down. It was defined as including 'The Baronies of - Lower Iveagh, Lower Half, and Lower Iveagh, Upper Half, and so much of the Barony of Iveagh Upper, Upper Half, as comprises the Parishes or parts of Parishes of - Aghaderg, Annaclone and Seapatrick.'. There was a boundary change altering this division in 1918, when the new Mid Down constituency was created, and West Down was redefined as including 'The rural district of Moira; the part of the rural district of Banbridge which is not included in the East Down Division; and the urban districts of Banbridge and Dromore.'. Maps showing the component units of the constituency can be seen here.

Prior to the United Kingdom general election, 1885 and after the dissolution of Parliament in 1922 the area was part of the Down constituency.

The constituency was strongly unionist in 1918, when Sinn Féin only polled 1,725 votes. Two subsequent by-elections produced unopposed returns for the Unionist candidates.

Sinn Féin contested the general election of 1918 on the platform that instead of taking up any seats they won in the United Kingdom Parliament, they would establish a revolutionary assembly in Dublin. In republican theory every MP elected in Ireland was a potential Deputy to this assembly. In practice only the Sinn Féin members accepted the offer.
