Izyaslav was first mentioned in 1390. It was a private town in Poland, owned by the Zasławski and Sanguszko families. It was part of the Polish Volhynian Voivodeship. In 1583 it was granted Magdeburg city rights.

After the Partitions of Poland Izyaslav was part of the Russian Empire – Volhynian Governorate.

At the beginning of World War II, the town had a Jewish population representing 28% of the inhabitants.^[5] As soon as the Germans occupied the town, Jews were kept imprisoned in a ghetto and were later murdered in mass executions perpetrated by Einsatzgruppen.^[6]

Until 18 July 2020, Iziaslav was the administrative center of Iziaslav Raion. The raion was abolished in July 2020 as part of the administrative reform of Ukraine, which reduced the number of raions of Khmelnytskyi Oblast to three. The area of Iziaslav Raion was merged into Shepetivka Raion.^[7][8]
