The Ostrogski family (Polish: Ostrogscy, Lithuanian: Ostrogiškiai, Ukrainian: Острозькі-Ostroz'ki, Belarusian: Астрожскія, "Астроскія", Russian: Острожские -Ostrozhskie) was one of the greatest Polish-Ruthenian families of the Grand Duchy of Lithuania. The family spanned from the 14th century (Daniil Ostrogski) to the 17th century. After the death of the last male heir of the Ostrogoski family, Janusz Ostrogski, most of the family's possessions were passed to the Zasławski family.

History
The Ostrogski family was most likely of Rurikid stock and descended from Sviatopolk II of Kiev. Some scholars however claim that their descent is from the Galicia-Volhynia line of the Rurikid dynasty. Vasilko Romanovich (c.1256-1282), Prince of Slonim, may have been the grandfather of Prince Daniel Ostrogski. The probable progenitor of this family was Prince Danylo Dmytrovych (or Danylo Wasilijewicz), who received Ostroh from Liubartas, King of Galicia-Volhynia and son of Grand Duke of Lithuania Gediminas. His son, Prince Feodor Danilovich Ostrogski, was a supporter of King Jagiello, who in 1386 confirmed him in possession of the Ostroh Castle and appointed governor of Volhynia in 1387. In addition to Ostrog Feodor Danilovich Ostrogski became owner of Korets, Zaslav (Izyaslav, in present Khmelnytskyi Oblast, Ukraine), and other towns. In some chronicles Feodor is called Dux Fethko de Ostrog. Their dominions in Volynia, Galicia, and Podolia included 24 towns, 10 townlets, and more than 100 villages.
The most notable among Feodor's descendants was Grand Hetman of Lithuania, Prince Konstanty Ostrogski, who defeated Muscovy in the Battle of Orsha (1514) and his son Konstanty Wasyl Ostrogski (or Konstantin Konstantinovich Ostrozhski). Unlike other Ruthenian magnates, the Ostrogskis refused to give up Eastern Orthodoxy for Roman Catholicism despite the cultural pressure that led to Polonization of Ruthenian nobility. For several generations the Ostrogskis supported the religion of their forefathers, by opening schools, printing books in Ruthenian language with Cyrillic such as "Ostrog Bible" (written by Ivan Fedorov) and making a generous charitable contributions to the construction of the Orthodox churches in the region.
The last male member of the family was Janusz Ostrogski (d. 1620); the last female was Anna Alojza Ostrogska (1600–54), married to Grand Hetman Jan Karol Chodkiewicz. When a junior line of the family (princes Zasławski or Zasławski-Ostrogowski) which inherited the Ostrogoski fortune became extinct in 1682 (with the death of Aleksander Janusz Zasławski), their huge possessions passed to the Lubomirski family (due to their marriage with Aleksander sister, Teofilia Ludwika Zasławska) and other families of Polish szlachta. A complicated litigation concerning the Ostrogski inheritance continued until the Russian Empire annexed Poland during the Partitions.
