The 2017 Northern Ireland Assembly election was held on Thursday, 2 March 2017. The election was held to elect members (MLAs) following the resignation of deputy First Minister Martin McGuinness in protest over the Renewable Heat Incentive scandal. McGuinness' position was not filled, and thus by law his resignation triggered an election.

Eight parties elected MLAs in the sixth assembly: the Democratic Unionist Party (DUP), Sinn Féin, the Ulster Unionist Party (UUP), the Social Democratic and Labour Party (SDLP), the Alliance Party of Northern Ireland, the Greens, People Before Profit (PBP), and Traditional Unionist Voice (TUV). There was also one Independent Unionist MLA.

It was the sixth election since the Assembly was re-established in 1998, and the first to implement a reduction in size to 90 MLAs (versus the previous 108).

1,254,709 people were registered to vote in the election (26,886 fewer, or a 2.1% decrease, compared to the 2016 Assembly election).^[2] 64.78% of registered voters turned out to vote in the 2017 Assembly election, up 9.8 percentage points from the previous Assembly election held in 2016, but 5 percentage points less than in the first election to the Assembly held in 1998.^[3]
