Fermanagh and South Tyrone is a parliamentary constituency in the British House of Commons. The current MP is Michelle Gildernew of Sinn Féin. Boundaries 1950–1983: The county of Fermanagh, the Urban District of Dungannon, the Rural Districts of Clogher and Dungannon, and that part of the Rural District of Omagh consisting of the district electoral divisions of Aghafad, Dervaghroy, Dromore, Drumharvey, Ecclesville, Fallaghearn, Fintona, Greenan, Killskerry, Lifford, Moorfield, Rahoney, Seskinore, Tattymoyle and Trillick. 1983–1997: The District of Fermanagh, and the District of Dungannon. 1997–present: The District of Fermanagh, and the District of Dungannon wards of Augher, Aughnacloy, Ballygawley, Ballysaggart, Benburb, Caledon, Castlecaulfield, Clogher, Coolhill, Drumglass, Fivemiletown, Killyman, Killymeal, Moy, Moygashel, and Mullaghmore. The constituency was created in 1950 when the old Fermanagh and Tyrone two-member constituency was abolished as part of the final move to single-member seats. As the name implies, it includes all of County Fermanagh and the southern part of County Tyrone. Of the post-1973 districts, it contained all of Fermanagh, and Dungannon and South Tyrone. In boundary changes resulting from a review in 1995, however, a section of Dungannon and South Tyrone (then called Dungannon) district, around the town of Coalisland, was transferred to the Mid Ulster constituency.

Many elections have seen a candidate from one community triumph due to multiple candidates from the other community splitting the vote. Perhaps because of this balance between the communities, Fermanagh and South Tyrone has repeatedly had the highest turn-out (and the smallest winning margin) of any constituency in Northern Ireland. The seat was won by the Nationalist Party in 1950 and 1951, the closely contested 1951 election seeing a 93.4% turnout – a UK record for any election. In 1955 the constituency was won by Philip Clarke of Sinn Féin, but he was unseated on petition on the basis that his criminal conviction (for Irish Republican Army activity) made him ineligible. Instead, the seat was awarded to the Ulster Unionist Party (UUP) candidate. In 1970 the seat was won by Frank McManus, standing on the "Unity" ticket that sought to unite nationalist voters behind a single candidate. In the February 1974 general election, however, the
