The Nation Alliance, abbreviated as NATION, was an electoral and political alliance in Turkey, made up of six opposition parties to contest the 2023 Turkish general election against its main rival, the People's Alliance. Originally established prior to the country's 2018 general election, the alliance had consisted of four opposition parties across the political spectrum, which had found common ground on withstanding Turkey's newly established presidential system. The alliance dissolved in 1 June 2023 following its narrow defeat in the 2023 elections, after the Good Party's announcement that they were no longer a part of it.

General elections took place on 14 May 2023. Presidential elections are held to elect the President of Turkey using a two-round system. Simultaneously, parliamentary elections are held to elect 600 Members of parliament to the Grand National Assembly of Turkey.
