Joseph Anton Friedrich Wilhelm Ihne (2 February 1821 – 21 March 1902) was a German historian who was a native of Fürth. He was the father of architect Ernst von Ihne (1848–1917).^[1]

He studied philology at Bonn, obtaining his degree in 1843 with a thesis titled Quaestiones Terentianae. From 1847 to 1849 he was a teacher in Elberfeld, afterwards moving to England, where he taught school in Liverpool until 1863. He returned to Germany as a lecturer at the University of Heidelberg, where in 1873 he was appointed professor. He died in Heidelberg.

Ihne is remembered for the classic Römische Geschichte (History of Rome), a work published in eight volumes from 1868 to 1890, and also translated into English. Other works on Roman history by Ihne include:
