The Grand Chancellor of Lithuania (; ; ) was one of the highest offices in the Grand Duchy of Lithuania. The office functioned from the middle of the 15th century until the end of the real union with the Kingdom of Poland in 1795 and its subsequent partition among Prussia, Russia and Austria. The expanding territory of the Grand Duchy of Lithuania and the increasing value of land, property as well as judicial institutions meant an increased need for written documents. The needs of Vytautas's political diplomacy with the Grand Duchy of Moscow, Byzantine Empire and tatars were met with the creation of two chancelleries - the first of which would prepare documents in Latin and German, while the second would prepare documents in Russian. Eleven scribes worked in those offices, some of whom were sent by Vytautas's cousin and king of Poland, Jogaila, from his estate in Poland (Mikalojus Cebulka and Mikalojus Maldrzykas are examples of such scribes). It is known that three scribes came from the Teutonic Order. Scribes from Volhynia were given the task of assisting in writing Ruthenian, although it is believed that some Ruthenian documents were prepared by Lithuanians. Up until the Union of Lublin the role of the Grand Chancellor would be the second highest next to the Grand Duke since he would usually reside in Poland and consequently Grand Chancellor oversaw most of the Grand Duchy's politics as well as the Lithuanian Council of Lords.
