The elections to the [[13th Nagaland Assembly|13th Nagaland State Legislative Assembly]] was held on 27th February 2018 in 59 out of its 60 constituencies, with one member elected unopposed. The counting of votes took place on 3rd March 2018. The incumbent [[Naga People's Front]] (NPF) lost the elections, while Chief minister [[T. R. Zeliang]] retained his seat. Former NPF leader, [[Neiphiu Rio]] joined the [[Nationalist Democratic Progressive Party]] (NDPP) before the elections. Subsequently, with two-thirds majority in the assembly, the NDPP-[[Bharatiya Janata Party]] alliance formed the government with Rio as the new Chief Minister of Nagaland.
