Vanessa Vadim (born 28 September 1968, in Paris) is a French American independent producer and cinematographer. She is the daughter of actress Jane Fonda and French filmmaker Roger Vadim.

In the 1990s she co-founded MayDay media with Brown University classmate Rory Kennedy. It is a non-profit production and distribution group that uses video as the center force in campaigns that fight racism, sexism, classism and homophobia. The company produced a short video called Fire in Our House about needle exchange programs and their ability to prevent the spread of HIV infections.

In 2002 a documentary she co-directed and produced with Matt Arnett called The Quilts of Gee's Bend was released. This film accompanies a museum exhibition and features the quiltmakers and quilts, historical photography and a musical soundtrack based on the gospel songs of Gee's Bend.

Vadim married Paul Van Winkle in France in June 2010.
