Zasławski (plural Zasławscy) (Ukrainian: Заславські) is a surname of Polish–Ruthenian nobility. The Zasławski family had its power base in Volhynia, Ukraine, and traced its origins to a branch of the Rurikids that took a name from the Zasław city (now Iziaslav). Due to their relation to the Rurikids, they held title of Knyaz (Prince).
Zasławski family was one of the three major families in the Polish–Lithuanian Commonwealth to trace its origins to the Ruthenian Rurikids; the other two families are the Ostrogski family & Wiśniowiecki family. The Zasławski family was sometimes seen as a junior line of the Ostrogoski, and after the last male heir of Ostrogoski family, Janusz Ostrogski, died in much of Ostrogoski possessions were inherited by Zasławcy. Nonetheless Zasławski family faced a similar fate to that of Ostrogoski: their last heir, Aleksander Janusz Zasławski, died in 1682. Their huge possessions passed to the Lubomirski (due to their marriage with Aleksander's sister, Teofilia Ludwika Zasławska) and other families of Polish szlachta. A complicated litigation concerning Ostrogski inheritance continued until Russian Empire annexed Poland during the Partitions.
