Gunnel Gunnarsdotter Hazelius-Berg née Hazelius (1905–1997) was a Swedish museum curator, textile researcher and writer.

Together with her daughter-in-law Inga Arnö-Berg, in 1975 she published Folkdräkter och bygdedräkter från hela Sverige which was translated into English as Folk Costumes of Sweden: A Living Tradition.

Her paternal grandfather Artur Hazelius had founded and directed the Nordic Museum and her father had taken it over for a few years until his early death in February 1905.

They were displayed separately on models in showcases protected by dampened lighting, complete with suitable period portraits and colour schemes.
