Archduke Albrecht Friedrich Rudolf Dominik of Austria, Duke of Teschen, was an Austrian Habsburg general. He was the grandson of Emperor Leopold II and one of the chief military advisors of Emperor Francis Joseph I. As Inspector General for 36 years, he was an old-fashioned bureaucrat who largely controlled the Austro-Hungarian Army and delayed modernization. He was honored with the rank of Field Marshal in the armies of Austria-Hungary (1863) and Germany (1893).

The Duchy of Teschen, also Duchy of Cieszyn or Duchy of Těšín, was one of the Duchies of Silesia centered on Cieszyn in Upper Silesia. It was split off the Silesian Duchy of Opole and Racibórz in 1281 during the feudal division of Poland and was ruled by Silesian dukes of the Piast dynasty from 1290 until the line became extinct with the death of Duchess Elizabeth Lucretia in 1653.
