"Unity" was the political label for a series of electoral pacts by Irish nationalist, Irish Republican and socialist candidates in Northern Ireland elections in the late 1960s and early 1970s. It also contested elections as a party in its own right, electing six councillors in the 1973 local council elections in the Fermanagh and Dungannon areas,^[1] although this was reduced to two members of Fermanagh council in the next election in 1977.^[2]

The first victory came in 1969 in the Mid Ulster by-election which was won by 21-year old student Bernadette Devlin.^[3] She held her seat in the 1970 general election,^[4] when Fermanagh and South Tyrone was won by her colleague Frank McManus.^[5] Both lost their seats in the February 1974 general election.^[6] Bernadette would later go on to join the IRSP. ^[7]

In the October 1974 general election the spirit of Unity was revived, if not the name, when Frank Maguire won Fermanagh and South Tyrone as an agreed independent Republican.^[8] He held the seat until his death in 1981.^[9] In 1978 Unity merged with the remnants of the Nationalist Party to form the Irish Independence Party.^[10]
