Fermanagh and South Tyrone (Irish: Fear Manach agus Tír Eoghain Theas, Ulster Scots: Fermanay an Sooth Owenslann) is a constituency in the Northern Ireland Assembly.

It usually shares boundaries with the Fermanagh and South Tyrone UK Parliament constituency.

However, the boundaries of the two constituencies were slightly different from 1983 to 1986 (because the Assembly boundaries had not caught up with Parliamentary boundary changes) and from 1996 to 1997, when members of the Northern Ireland Forum had been elected from the newly drawn Parliamentary constituencies but the 51st Parliament of the United Kingdom, elected in 1992 under the 1983–95 constituency boundaries, was still in session.

Note: Austin Currie, John Taylor and Harry West were all members of the House of Commons of Northern Ireland when it was prorogued in 1972.
