Joseph Georg Friedrich Ernst Karl, Duke of Saxe-Altenburg (27 August 1789 in Hildburghausen – 25 November 1868 in Altenburg), was a duke of Saxe-Altenburg.
He was the second but first surviving son of Frederick, Duke of Saxe-Hildburghausen (of Saxe-Altenburg from 1826) and Duchess Charlotte Georgine of Mecklenburg-Strelitz.
Joseph succeeded his father as Duke of Saxe-Altenburg after his death in 1834.
In 1814, he and his brother George fought with the allies against France in the Napoleonic Wars.
Later he was a General Major in Saxon services.
He implemented several buildings in Altenburg, but his government was considered conservative and resistant to reform; for this, he was forced to abdicate during the civil revolution of 1848.
