Vanishing Wilderness is a 1973 American wilderness documentary from Arthur Dubs who established Pacific International Enterprises. It was filmed by Heinz Sielmann. Areas covered included Oregon's Rogue River, the Arctic Circle, Alaska and the Florida Everglades.

In contrast with Dubs' previous documentary, American Wilderness, which focused on hunting, Vanishing Wilderness was more of a family film and was rated "G".

The film received endorsements from then-Governor Ronald Regan and John Wayne.
