Mac Ahlberg (12 June 1931 – 26 October 2012) was a Swedish film director and cinematographer.

[2] The first feature Ahlberg directed was the Danish erotic classic I, a Woman (Denmark, 1965) which went on to international success, especially in the United States.

He quickly became identified with erotic fare, directing two sequels to I, a Woman[3][4] as well as a Swedish version of Fanny Hill (Sweden, 1968), starring Diana Kjær and Oscar Ljung.

Ahlberg moved to the United States in the late 1970s and worked mostly as a cinematographer on American productions; he was frequently hired by producer Charles Band, and worked on such Band productions as Re-Animator (1985), From Beyond (1986), and Dolls (1987), all three of which were directed by Stuart Gordon.

[citation needed] Ahlberg died from complications of congestive heart failure on 26 October 2012.
