The Mid Ulster by-election was held on 17 April 1969 following the death of George Forrest, the Ulster Unionist Party Member of Parliament for Mid Ulster. The two-way contest was unusual in featuring two female candidates. Forrest had held the seat since 1956, initially winning it as an Independent Unionist, but joining the Ulster Unionist Party (UUP) immediately on his election. The seat had been created six years earlier, and during that period had been held by two Nationalist Party members, one Sinn Féin member, and an Ulster Unionist.
