The 2017 United Kingdom general election in Northern Ireland was held on 8 June 2017. All 18 seats in Northern Ireland were contested. The DUP gained 2 seats for a total of 10, and Sinn Féin won 7, an improvement of 3. Independent unionist Sylvia Hermon was also elected in her constituency of North Down. Meanwhile, the SDLP lost 3 seats and the UUP lost 2 seats. Both lost their representation at Westminster.

As Sinn Féin candidates maintain a policy of abstentionism in regards to the British Parliament, the 2017 election marked the first parliament since the 1964 without any Irish nationalists.

Nationally, the governing Conservative 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 holds the balance of power, and announced on 10 June that it would support the incumbent government for confidence votes in Parliament.

Five seats changed hands in Northern Ireland. The SDLP lost its seats in Foyle and South Down to Sinn Féin and the constituency of Belfast South to the DUP. Meanwhile, the UUP lost South Antrim to the DUP and Fermanagh and South Tyrone to Sinn Féin. The number of unionist and nationalist representatives (11 and 7, respectively) remained unchanged from the 2015 election, although none of the nationalist members intend to participate in the next parliament.
