Dungannon was a United Kingdom Parliament constituency, in Ireland, returning one MP. It was an original constituency represented in Parliament when the Union of Great Britain and Ireland took effect on 1 January 1801 and was abolished by the Redistribution of Seats Act 1885. This act split County Tyrone into four single-member constituencies: East Tyrone, Mid Tyrone, North Tyrone and South Tyrone. It took effect at the 1885 United Kingdom general election.
