Tiszaújváros (Hungarian pronunciation: [ˈtisɒuːjvaːroʃ]; Slovak: Nové Mesto nad Tisou) is an industrial town in Borsod-Abaúj-Zemplén county, Northern Hungary, 35 km (22 mi) south-east of Miskolc, near the river Tisza.

Tiszaújváros as a town owes its existence to the industrialization wave that took over the then-socialist Hungary after World War II.

The government wanted to speed up industrial development and create new job opportunities in the north-eastern part of the country.

[1] The construction of the town began on 9 September 1955; among the first buildings was a thermal power station and some blocks of flats around it.

It is one of the major chemical complexes in Hungary and, according to their website, represents more than 20% of petrochemical capacities in Central Europe.
