The County of Saarwerden (German: Grafschaft Saarwerden; French: Comté de Sarrewerden) was a county located in Lorraine, within the Holy Roman Empire. As a second-level fief, it belonged to its local ruler and not to the emperor. Its capital was in Bockenheim (situated on the right side of the Saar) and later in New Saarwerden or Ville Neuve de Sarrewerden (on the left side of the Saar), both in the present city of Sarre-Union. Today, the area of the county belongs to Bas-Rhin, Alsace.
