The Duchy of Saxe-Lauenburg (, ), was a reichsfrei duchy that existed from 1296 to 1803 and again from 1814 to 1876 in the extreme southeast region of what is now Schleswig-Holstein. Its territorial centre was in the modern district of Herzogtum Lauenburg and originally its eponymous capital was Lauenburg upon Elbe, though the capital moved to Ratzeburg in 1619.
