Matilda of Swabia (c. 1048 – 12 May 1060), a member of the Salian dynasty, was the daughter of Emperor Henry III from his second marriage with Agnes of Poitou.
Among her older siblings were Adelaide, who became Abbess of Quedlinburg and Gandersheim, and Gisela, who died in infancy.
Her younger siblings included her brothers Henry IV, who succeeded their father as Holy Roman Emperor in 1056, and Conrad II, who also died in infancy, and a sister, Judith of Swabia, who was queen consort of Hungary from 1063 to 1074.
In addition, Matilda had an older half-sister, Beatrix, Abbess of Quedlinburg and Gandersheim, born from her father's first marriage with Princess Gunhilda of Denmark.
