Adolf or Adolph (c. 1255 – 2 July 1298) was the King of Germany from 1292 until 1298. His title in his lifetime was rex Romanorum, but he is usually known as Adolf of Nassau.
He had neither influence nor power, and was elected to become King of the Romans because of the electors' preference for a weak king. His election was largely secured through the influence of the elector-archbishops of Mainz and Cologne. He was crowned King of the Germans (Emperor-Elect) on June 2, 1292, at Aachen. He was never crowned by the pope in Rome, which would have secured him the title of Emperor.
He founded the convent of Clarenthal near Wiesbaden in 1296.
