The Hungary–Ukraine border (Hungarian: magyar–ukrán államhatár; Ukrainian: Угорсько-український кордон) is an internationally established boundary between Hungary and Ukraine. The modern border remains unchanged since the end of the World War II.The current border was established after World War II when Zakarpattia Oblast was admitted into Ukraine, which at the time was part of the Soviet Union as the Ukrainian Soviet Socialist Republic. The border stretches for 136.7 km (84.9 mi) along the Tisza river valley.
After the admission of Hungary to the European Union, the border security became the responsibility of the union, as well.
