Gisela's third marriage, which took place before January 1017, was to Conrad II, who was elected king of Germany in 1024 and became emperor of the Holy Roman Empire in 1027.
According to Thietmar of Merseburg, Archbishop Aribo of Mainz refused to crown her as queen because Gisela and Conrad were too closely related, the couple both descending from King Henry the Fowler.
She was instead crowned thirteen days after Conrad's coronation by Archbishop Pilgrim of Cologne.
For the same reason, Henry II replaced her as her son's regent with Poppo of Trier, which became the source of conflict between Conrad and Henry.

Gisela played an active part in politics, attending Imperial councils and having her uncle King Rudolph III of Burgundy transfer the succession of his Arelat realm to her husband Conrad.
Also, she participated in several synods of the church.
She took care of her sister Matilda's daughters Sophie and Beatrice, who later ruled Bar and Tuscany respectively.
After Conrad's death in 1039, she and her son Henry III led the mourning progression.

The empress died of dysentery at the Imperial Palace of Goslar in 1043.
She is interred in the grotto of Speyer Cathedral, Germany along with several emperors and other members of the imperial family.
Her tomb was opened in 1900 and Gisela's mummified body was found to be 172 cm (5' 8") tall, with long blond hair.
