Jász-Nagykun-Szolnok is the name of an administrative county (comitatus) in the former Kingdom of Hungary. Its territory, which is presently in central Hungary, was slightly smaller than that of present Jász-Nagykun-Szolnok county. The capital of the county was Szolnok.
Jász-Nagykun-Szolnok county was formed in the 19th century from the territories of Szolnok, Jászság (Jazygia) and Nagykunság (great Cumania). After World War II, the territory of the county was modified: the area on the left bank of the Tisza around Tiszafüred was taken from Heves county, and the area around Dévaványa went to Békés county.
The term Jász originates from the Jassic people (cf. Alans) who moved to this area of Hungary from the Pontic steppes sometime in the 13th century.
