Czetwertyński or Chetvertynsky (also Sviatopolk-Chetvertynsky) is a Ukrainian (or Polish) princely family originated from Volhynia in the Crown of the Kingdom of Poland. The family takes its name from the village of Chetvertnya, Lutsk county, in modern-day Manevychi Raion, Volyn Oblast.
In 1492 Prince Fedir Mykhailovych Chetvertynsky was the Lithuanian-Ruthenian ambassador to Wallachia. Over time some members of the family were Catholicized, but mostly the family remained adherent to the Eastern Orthodox religion.
Prince Stepan Sviatopolk-Chetvertynsky (1575-1659) played a key role in reestablishing the Ukrainian Orthodox Church of the Ecumenical Patriarchate of Constantinople in 1620. His son Mykola Sviatopolk-Chetvertynsky (?-1659) was a relative of the Hetman of Zaporizhian Host Ivan Vyhovsky.
Two of the most notable representatives of the family were Hedeon Zakharovych Svyatopolk-Chetvertynsky, the Metropolitan of Kiev, Galicia and all Little Russia in 1685-90, and Antoni Stanislaw's daughter Marie who was Alexander I of Russia's mistress and had children by him. Nephew of Hedeon, Yurii Sviatopolk-Chetvertynsky (?-ca 1717–22) was a son-in-law of the Hetman of Zaporizhian Host Ivan Samoylovych.
After Antoni Stanisław Czetwertyński-Światopełk was lynched in 1794 by Polish nationals in Warsaw (Russian Empire) during the Kościuszko Uprising, his family resettled in Saint Petersburg. It received major land grants from Catherine the Great such as the manor of Filimonki near Moscow.
