Leix, a division of Queen's County, was a constituency in Ireland, returning one Member of Parliament to the United Kingdom House of Commons from 1885 to 1918.
Prior to the 1885 general election and after the dissolution of Parliament in 1918 the area was part of the Queen's County constituency. From the time of Irish independence, it was not represented in the UK Parliament, as Laois was no longer part of the United Kingdom.
