Adelaide of Vohburg (German: Adela or Adelheid; c. 1125 – 25 May after 1187) was Duchess of Swabia from 1147 and German queen from 1152 until 1153, as the first wife of the Hohenstaufen king Frederick Barbarossa, the later Holy Roman Emperor.

Adelaide was a daughter of the Bavarian margrave Diepold III of Vohburg (c. 1079 – 1146), probably from his first marriage with Adelaide (Adelajda; c. 1091 – 1127), a daughter of the Polish duke Władysław I Herman and Judith of Swabia. Since the days of Emperor Henry IV, her father's ancestors ruled over the Egerland territory in the Bavarian March of the Nordgau, which, however, was seized by King Conrad III of Germany upon the margrave's death in 1146.

In turn, King Conrad married his nephew Frederick of Hohenstaufen to late Diepold's daughter Adelaide before 2 March 1147 in the city of Eger. The young man had just returned from the Second Crusade; he succeeded his father Frederick the One-Eyed as Duke of Swabia one month later and added his wife's extended dowry to his estates. However, the marriage was not a happy one, according to the historian Friedrich von Raumer (1781–1873) probably due to adultery committed by Adelaide. She rarely made public appearances and was not even present, when Frederick managed to be elected as the successor of his paternal uncle on 4 March 1152 and was crowned King of Germany at Aachen Cathedral five days later.
