War of the Satellites is a 1958 independently made American black-and-white science fiction film drama, produced and directed by Roger Corman, and starring Richard Devon, Dick Miller and Susan Cabot. It was distributed in the U.S. and the U.K. by Allied Artists. In the U.S., it was released as a double feature with Attack of the 50 Foot Woman.

The low-budget feature was rapidly conceived, filmed and released to exploit the international media frenzy around the launch of the Russian Sputnik satellite, the first in space.

In the film, an "unknown force" declares war against Earth when the United Nations disobeys its warnings against assembling and launching the first satellite into space.
