Sophia of Formbach (also Sophia of Vormbach) (c. 1050/5 – after 1088), was the daughter of Meginhard IV of Formbach. She was countess of Salm through her marriage to Hermann of Salm, who was also elected German anti-king from 1081 to 1088.

Sophia was the daughter of Meginhard IV of Formbach and Matilda of Reinhausen, a daughter of Count Elli.^[1] Sophia married Hermann of Salm. The couple were closely related and there were attempts to separate them on these grounds.^[2] Hermann died in 1088. It is sometimes said that Sophia married for a second time around 1092 to Stephan II, Count of Sponheim, although this is not certain.^[3]

Sophia, like the rest of her natal dynasty (the Formbachs), was a patron of Göttweig Abbey.^[4]

With her first husband, Hermann, Sophia had the following children:

• Otto I, Count of Salm
• Hermann II of Salm (1087–1135)
• Dietrich of Salm (fl. 1095)

If she married Stephan II of Sponheim, then Sophia was also the mother of:

• Meginhard I, Count of Sponheim
• Jutta (1090-1136), founder of the female convent at the abbey of Disibodenberg^[5]
• Hugh of Sponheim, archbishop of Cologne (1137)
