Saxe-Gotha-Altenburg (Lua error in package.lua at line 80: module 'Module:Language/data/iana scripts' not found.) was a country in what is today Thuringia, Germany.

It was formed in 1672 when Frederick Wilhelm III, the last duke of Saxe-Altenburg died and Ernest I, Duke of Saxe-Gotha (who had married Frederick Wilhelm's cousin, Elisabeth Sophie) inherited his possessions.

The duchy was split up again after Ernest’s death in 1675, and the Duchy of Saxe-Gotha-Altenburg officially came into existence in 1680 when his eldest son, Frederick, took control of the parts of the country Gotha and Altenburg.

When the royal house of Saxe-Gotha and Altenburg became extinct in 1825, Saxe-Gotha was given to Saxe-Coburg-Saalfeld and Saxe-Altenburg passed to the Duke of Saxe-Hildburghausen. After the abolition of German monarchies at the end of the First World War, both Saxe-Gotha and Saxe-Altenburg became part of the newly created state of Thuringia in 1920.
