It is situated on the right side of the Zbruch River, opposite Volochysk in neighboring Khmelnytskyi Oblast. Pidvolochysk hosts the administration of the Pidvolochysk settlement hromada, one of the hromadas of Ukraine. Population: 7,632 (2022 estimate).

Around 1910, Pidvolochysk, the town - like the rest of the then Austrian Galicia - was part of the Austro-Hungarian Empire. Before World War II, a majority of the inhabitants were Jewish.

In July 1941, Germans created a labor camp for the Jews. In 1942 part of the prisoners were transported to Zbaraż and Kamionka. In October 1942, the transport was sent to Bełżec extermination camp. The final annihilation, of those who were left, took place during the liquidation of the camp on 29 June 1943.

The Podwolocyska Organization was headed by Bernard Lerner (died 1988), later headed by Borekh Goldshteyn.) who published an account of WWII era

Until 18 July 2020, Pidvolochysk was the administrative center of Pidvolochysk Raion. The raion was abolished in July 2020 as part of the administrative reform of Ukraine, which reduced the number of raions of Ternopil Oblast to three. The area of Pidvolochysk Raion was merged into Ternopil Raion.

Until 26 January 2024, Pidvolochysk was designated urban-type settlement. On this day, a new law entered into force which abolished this status, and Pidvolochysk became a rural settlement.

It was also the birthplace (1910) of fringe Israel Scheib (later Eldad), radical nationalist Israeli politician and a leader of the anti-British Lehi underground organization.
