Paul Dax (1503–1561) was an Austrian artist.
Dax was born in the Tyrol. He led a very unsteady life, and after having gained reputation as a painter, he gave up art, and entered the army, engaging in several campaigns and the sieges of Naples, Florence, and Vienna. In 1530 he devoted himself to glass-painting, and his works, which are of considerable merit, are now in the court-house of Innsbruck, and in the town-hall at Ensisheim, Alsace. He also published several maps of his country. His death occurred in 1561.
