Olbracht Gasztołd was a Polish-Lithuanian noble of the House of Gasztołd from ethnic Lithuanian lands of the Grand Duchy of Lithuania. Voivode of Navahrudak since 1508, Voivode of Polotsk since 1514, Voivode of Trakai since 1519 and Voivode of Vilnius since 1522. In 1522 he became Grand Chancellor of Lithuania. He was the initiator and the editor of the First Statute of Lithuania, as a successor of his staunch opponent Mikolaj Radziwiłł, who rivaled him in the precedence in the Council of Lords. His subsequent rival in influence in the Grand Duchy was Konstanty Ostrogski. In 1529, he received the title of count from Pope Clement VII, and in the following year, thanks to the efforts of Jan Dantyszek, he received the title of Graf of Murowane Gieranojny from Emperor Charles V.

The House of Gasztold was a family of the Grand Duchy of Lithuania, one of the most influential magnate of families of its region during the 15th and early 16th centuries. Their only serious rivals were the Kieżgajło, and from the end of the 15th century the fast rising in power and influence Radziwiłł family clan. It appears from the Latin original spelling of their name Gastoldus which is a variation of castaldius that they had been close to the Grand Dukes and that their function was to oversee ducal demesne. Most power family gained during the reign of Casimir Jagiellon. The castaldius of Vytautas, Andrius Goštautas might have been a voivode of Vilnius and Kreva, and father of Jonas, appears to have been the precursor of the family growth. The majority of the family's possessions (lands) were in the western part of the Duchy and eastern ethnic Lithuania. After the death of the last scion of the family, Stanisław Gasztold, the Polish King and Grand Duke of Lithuania Sigismund II Augustus inherited his possessions as a matter of right, per Grand Duchy of Lithuania law.
