Gunn Wållgren (16 November 1913 – 4 June 1983) was a Swedish actress.

Considered one of Sweden's finest and also to date most appreciated actresses, Wållgren was famous for her fragile and sensual way of acting, her warm and rich inner soulfulness, and her never failing ability of presenting an absolute presence and naturalness on stage. Her Chekhov and Ibsen character interpretations, in particular, are considered to be unsurpassed.
