The Ogiński, feminine form: Ogińska, plural: Ogińscy (Lithuanian: Oginskiai, Belarusian: Агінскія, Ahinskija) was a noble family of Grand Duchy of Lithuania and Poland (later, the Polish–Lithuanian Commonwealth), member of the Princely Houses of Poland.
They were most likely of Rurikid stock, related to Chernihiv Knyaz family, and originated from the Smolensk region, incorporated into the Grand Duchy of Lithuania in approximately the fourteenth century. The family bears its name from Uogintai (in present-day Kaišiadorys district of Lithuania), a major estate of the family in Lithuania that was granted to precursor of the family, Knyaz Dmitry Hlushonok (d. 1510), by Grand Duke of Lithuania Alexander in 1486.
An important family in the Grand Duchy of Lithuania, the family had produced many important officials of the state, as well as several notable musicians. The political stronghold of the Ogiński clan was the Vitebsk Voivodeship, where a palace was built in the first half of the seventeenth century by Samuel Ogiński. Until the beginning of the nineteenth century, it was the largest public building in the city of Vitebsk.
On September 18, 1711 Bishop Bogusław Gosiewski, sold the town of Maladzyechna to the Ogiński family. Among the owners of the area were Kazimierz Ogiński and Tadeusz Ogiński, the Castellan of Trakai. The Ogiński family made it one of the main centres of their domain. They erected a new, classicist palace with notable frescoes, as well as a late renaissance church. In 1783 the family received the title of Prince from the Holy Roman Emperor. The continued existence of the family is noted among charts of the Princely Houses of Poland.
