Gustav Storm (18 June 1845 – 23 February 1903) was a Norwegian historian, a professor at the Royal Frederick University in Christiania from 1877.

When Gustav was five years old, his father died, and the family subsequently moved to Christiania (now Oslo).

Among his works were Snorre Sturlassøns Historieskrivning, en kritisk Undersøgelse from 1873, and his thesis Sagnkredsene om Karl den Store og Didrik af Bern hos de nordiske Folk from 1874.

His translation of Heimskringla into Norwegian in the late 1890s was the basis for a popular edition of Snorri Sturluson's work.
