Albert Blar Brudzewski, Wojciech Brudzewski, Albert Blar of Brudzewo (Latin: Albertus de Brudzewo) (1445 in Brudzewo, Masovia – 1497 in Vilnius) was a Polish astronomer, mathematician and prominent professor at the Akademia Krakowska in Cracow, where he stayed for twenty years.

Albert Blar was born in Brudzewo, duchy of Masovia and was educated at the Charles University in Prague. His study material was Georg von Peuerbach's Theory of the Planets and Regiomontanus' Astronomical Tables. He gave his last astronomical course at Cracow in 1490.

His most famous pupil was Nicolaus Copernicus, who enrolled after 1490, at a time when Albert Brudzewski only taught about Aristotle. It is possible that Copernicus may have had some private discussions with Blar of Brudzewski, since Brudzewski was in close contact to students due to his position as head of a student dormitory, called Bursa Hungarorum.

Albert Blar of Brudzewski left Cracow in 1494 and went to Vilnius as secretary to Aleksander Jagiellon, Grand Duke of Lithuania, who later also became king Alexander of Poland.
