The Good Party (Turkish: İYİ Parti) is a nationalist, Kemalist and conservative political party in Turkey, established on 25 October 2017 by Meral Akşener. The party's name and flag is a reference to the tamga of the Kayı tribe.
The party was formed as a result in a split by prominent former members of Turkey's Nationalist Movement Party (MHP) and later joined by some former members of the main opposition Republican People's Party (CHP). The party's founder and chairperson, Meral Akşener, and its deputy chairperson, Koray Aydın, are both former members of the MHP before establishing the party. Plans to form a new party emerged amongst prominent MHP defectors after the MHP's support for a 'Yes' vote in the controversial 2017 constitutional referendum, as well as a failed attempt to unseat the party's governing leader. In addition to endorsing a more moderate civic nationalism as opposed to the ardent ethnic nationalism of the MHP, the party runs on an anti-establishment platform criticising both the governing and opposition parties in Turkey for their ineffectiveness. The party describes itself as being in the centre of political spectrum though third-party sources have described the party as being centre-right or on the right-wing of the political spectrum.
