Gisela of Swabia (c. 990 – 15 February 1043), was queen of Germany from 1024 to 1039 and empress of the Holy Roman Empire from 1027 to 1039 by her third marriage with Emperor Conrad II. She was the mother of Emperor Henry III. She was regent of Swabia for her minor son Duke Ernest II of Swabia in 1015, although it seems at that time her husband Conrad was the one who held the reins of government, leading to the enmity between stepfather and stepson.
