The2017 United Kingdom general election in Northern Ireland was held on 8 June 2017. All 18 seats in Northern Ireland were contested. 1,242,698 people were eligible to vote, up 5,933 from the 2015 general election. 65.6% of eligible voters turned out, an increase of 7.2 percentage points from the last general election.^[1]

TheDUP gained 2 seats for a total of 10, andSinn Féin won 7, an improvement of 3. Independent unionistSylvia Hermon was also re-elected in her constituency ofNorth Down. Meanwhile, theSDLP lost 3 seats and theUUP lost 2 seats, meaning they both lost all their representation in theHouse of Commons.

As Sinn Féin maintains a policy ofabstentionism in regards to the British Parliament, the 2017 election marked the first parliament since1964 without anyIrish nationalist MPs who take their seats in the House of Commons in Westminster.

Nationally, the governingConservative Party fell 8 seats short of a parliamentary majority after the election, reduced to 4 if the absence of Sinn Féin is taken into account. The DUP thus held thebalance of power, and announced on 10 June that it would support the Conservative government on a "confidence and supply" basis.^[2](See alsoConservative–DUP agreement.)

Five seats changed hands in Northern Ireland. The SDLP lost its seats inFoyle andSouth Down to Sinn Féin and the constituency ofBelfast South to the DUP. Meanwhile, the UUP lostSouth Antrim to the DUP andFermanagh and South Tyrone to Sinn Féin. The number of unionist and nationalist representatives (11 and 7, respectively) remained unchanged from the2015 general election, although none of the nationalist members participated in theParliament.
