I Am Curious (Yellow) (original Swedish title: Jag är nyfiken - gul) is a 1967 Swedish film directed by Vilgot Sjöman and starring Lena Nyman as a character named after her. It is a companion film to 1968's I Am Curious (Blue); the two were initially intended to be one 3½ hour film. The films are named after the colours of the Swedish flag.
The film includes numerous and frank scenes of nudity and staged sexual intercourse. In one particularly controversial scene, Lena kissed her lover's flaccid penis.

Karalexis, 396 U.S. 976 (1969) and 401 U.S. 216 (1971)), the Second Circuit Court of Appeals found the movie not to be obscene.
