The Academic Gymnasium Danzig was a school founded in Gdańsk, Poland. It was founded in 1558 by Johann Hoppe (1512–1565), who had previously worked at schools in Kulm and Elbing until Catholic Prince-Bishop Stanislaus Hosius closed them. For most of its existence it had a character similar to that of a university.

Gottfried Lengnich was an 18th-century historian, lawyer and politician. He became known for writing the 9-volume History of Royal Prussia and for teaching Stanisław August Poniatowski, the last king of Poland.
