Carl Richard Unger (2 July 1817 – 30 November 1897) was a Norwegian historian and philologist.

[1] Unger was professor of Germanic and Romance philology at the University of Christiania from 1862[1] and was a prolific editor of Old Norse texts.

[1] Between 1830 and 1832 he lived in Telemark with the poet and priest Simon Olaus Wolff.

[1] Unger studied philology after school but did not receive a degree as mathematics, a subject with which he struggled, was compulsory for philologists.

[1] However, in 1841 he was awarded a scholarship to continue studying Old Norse, Old English and Old German.
