Szabolcs–Szatmár–Bereg (Hungarian: Szabolcs-Szatmár-Bereg vármegye, pronounced [ˈsɒbolt͡ʃ ˈsɒtmaːr ˈbɛrɛɡ]) is an administrative county (Hungarian: vármegye) in northeastern Hungary, bordering Slovakia (Košice Region), Ukraine (Zakarpattia Oblast), and Romania (Bihor and Satu Mare counties).

It borders Ukraine (Zakarpattia Oblast), Slovakia (Košice Region), and Romania (Bihor and Satu Mare counties), and has good connections both by road and rail.

The early Hungarians transformed this region significantly by clearing large areas of forest to make way for pastures and farmland.

Approximately 5 to 6 square kilometres of forest were cleared for the construction of the Szabolcs earthwork in the ninth and tenth centuries, and its ruins are still present.

The area was the gateway for the Mongol invasion of Hungary in the 1240s, and suffered considerable destruction and population decrease during the raids.

Tisza is one of the most important rivers of the county, entering Szabolcs-Szatmár-Bereg — and Hungary — at Tiszabecs, and leaving at Tiszadob.

The northern part of Nyírség is covered with sandy forest soils, the southern areas have loose wind-blown sand.

The higher than average number of days of sunshine make ideal conditions for the growing of tomatoes, sunflower, tobacco, apples, and other fruits such as plums—for which the county is famous, being eaten fresh, dried into prunes (some made into lekvar) and fermented into well-known brandies.

The eastern part of the county is lightly populated and is dotted with small villages which often have very poor economic conditions.

The railway border crossing toward Ukraine is well developed; its high capacity is able to meet the requirements of transit and bilateral trade.

There is a shortage of local capital and inward investment, which restrains the creation of new jobs, thus the unemployment rate remains the second highest in Hungary.
