Carl L. Thunberg, FSAScot (born 25 October 1963) is a Swedish popular historian.

[12] He also made a guest appearance on Lindgren’s punk band Loud Pipes' debut album The Downhill Blues in 1997.

From 2010 to 2012 he took part in the policy struggle to preserve the archaeological reconstructions at Gene fornby near Örnsköldsvik in Sweden.

[17][18][19][20] In 2021, Thunberg was one of ten archaeologists and historians who evaluated two very controversial findings presented by archaeologist Sven Rosborn: the Curmsun Disc, an artifact claimed to originate from Harald Bluetooth’s alleged grave in the ruined church in the village of Wiejkowo in Pomerania (now part of Gmina Wolin, Poland), and a transcription of an alleged medieval manuscript, Gesta Wulinensis ecclesiae pontificum.

[23][24] In 2023 Thunberg became chairman of the Swedish antiquities fund Stiftelsen Björkå AB Fornminnesfond, a foundation for financial contributions to science within archaeological areas, and research grants for scholarly projects involving protected historic buildings, archaeological sites and ancient remains.
