According to the official regional history, on the territory of the former Nedryhailiv Raion settlements were formed during the late
Paleolithic Era (as early as 15,000 years ago), lasting through the Bronze Age and into early Iron Age. In addition to these settlements, archaeologists discovered evidence of the
Chernyakhov and Maryanivska cultures,
Kurgan burial grounds of the
Scythian era, and remains of a settlement of the early Slavs from the first centuries A.D. The area in the region was populated by
Severian settlers during the
Kievan Rus' period. Archaeological excavations in 1972 uncovered artifacts from this period, including early
Slavic pottery, a beaded necklace, and remnants of metallic weaponry. It is likely that the ancient settlement of Nedryhailiv ceased to exist after the
Mongolian-Tatar Invasion of 1239. The area is believed to have remained uninhabited for almost three centuries afterward. With time, this land became part of the
Grand Duchy of Lithuania, and from the year 1569, the western part of Nedryhailiv Raion broke off to the Partitions of the
Polish–Lithuanian Commonwealth, where it stayed until 1647. The eastern and southeastern parts of the raion joined the
Grand Duchy of Moscow. The date is not precisely known when Nedryhailiv was established as an official township or population center. The official history estimates that the town was established no later than 1632, but another version of the town history has put it as being officially founded in 1639 by an officer of the Polish army.
Urban-type settlement since 1958. In January 1989 the population was 6604 people. In January 2013 the population was 5716 people. On 26 January 2024, a new law entered into force which abolished the urban-type settlement status, and Nedryhailiv became a rural settlement. == Transportation ==
