Starokostiantyniv (Ukrainian: Старокостянтинів; Polish: Starokonstantynów, or Konstantynów; Yiddish: אלט-קאָנסטאַנטין Alt Konstantin) is a city in the Khmelnytskyi Oblast (province) of western Ukraine. Population: 34,455 (2020 est.)
Starokostyantyniv was founded in the 16th century when Konstanty Ostrogski built a fortress at the village of Kolishchentsi. The surviving Starokostiantyniv Castle was constructed by his son between 1561 and 1571. The village grew into a town which became known as "Old Constantine's Town" (Kostiantyniv Staryi) to prevent confusion with "New Constantine's Town" in the vicinity. It became a private town of Poland, owned by the Ostrogski family. It was part of Polish Volhynian Voivodeship. 1648 saw the Battle of Starokostiantyniv.
In 1939, 6,743 Jews were living in the city, accounting for 31 percent of the total population. The Jewish community was murdered in mass executions perpetrated from August 1941 until November 1942.
