Peter Fredrik Wahlberg (19 June 1800, in Gothenburg – 22 May 1877, in Stockholm) was a Swedish entomologist and professor at the University College of Stockholm.
Wahlberg was a member of the Royal Swedish Academy of Sciences from 1830, and served as the academy's secretary from 1848 to 1866.[1]
The island Wahlbergøya, the largest of Vaigattøyane, is named after him.[1]
