The Lublin Triangle (Lithuanian: Liublino trikampis; Polish: Trójkąt Lubelski; Ukrainian: Люблінський трикутник, Liublinskyi trykutnyk) is a regional alliance of three European countries – Lithuania, Poland, and Ukraine – for the purposes of strengthening mutual military, cultural, economic and political cooperation and supporting Ukraine's integration into the European Union and NATO. The Lublin Triangle initiative invokes the integrative heritage of the 1569 Union of Lublin.
