Agnes of Waiblingen (1072/73 – 24 September 1143), also known as Agnes of Germany, Agnes of Poitou and Agnes of Saarbrücken, was a member of the Salian imperial family. Through her first marriage, she was Duchess of Swabia; through her second marriage, she was Margravine of Austria.
In 1079, aged seven, Agnes was betrothed to Frederick, a member of the Hohenstaufen dynasty; at the same time, Henry IV invested Frederick as the new duke of Swabia. The couple married in 1086, when Agnes was fourteen. They had twelve children, eleven of whom were named in a document found in the abbey of Lorsch:
- Hedwig-Eilike (1088–1110), married Friedrich, Count of Legenfeld
- Bertha-Bertrade (1089–1120), married Adalbert, Count of Elchingen
- Frederick II of Swabia
- Conrad III of Germany
- Heinrich (1096–1105)
- Beatrix (1098–1130), became an abbess
- Kunigunde-Cuniza (1100–1120/1126), wife of Henry X, Duke of Bavaria (1108–1139)
- Sophia, married Konrad II, Count of Pfitzingen
- Fides-Gertrude, married Hermann III, Count Palatine of the Rhine
- Richildis, married Hugh I, Count of Roucy
Following Frederick's death in 1105, Agnes married Leopold III (1073–1136), the Margrave of Austria (1095–1136). According to a legend, a veil lost by Agnes and found by Leopold years later while hunting was the instigation for him to found the Klosterneuburg Monastery.
Their children were:
- Leopold IV
- Henry II of Austria
- Berta, married Heinrich of Regensburg
- Agnes, "one of the most famous beauties of her time", married Wladyslaw II of Poland
- Uta, wife of Liutpold von Plain
- Otto of Freising, bishop and biographer
- Conrad, Bishop of Passau, and Archbishop of Salzburg
- Elisabeth, married Hermann, Count of Winzenburg
- Judith, m. c. 1133 William V of Montferrat. Their children formed an important Crusading dynasty.
- Gertrude, married Vladislav II of Bohemia
According to the Continuation of the Chronicles of Klosterneuburg, there may have been up to seven other children (possibly from multiple births) stillborn or who died in infancy.
In 2013, documentation regarding the results of DNA testing of the remains of the family buried in Klosterneuburg Abbey strongly favor that Adalbert was the son of Leopold and Agnes.
