Firefox is a 1982 American action techno-thriller film produced, directed by and starring Clint Eastwood. It is based upon the 1977 novel of the same name by Craig Thomas.

The film was set in Russia, but Cold War considerations had Eastwood's and Fritz Manes's Malpaso Company using Vienna and other locations in Austria to double for many of the Eurasian story locations. One source indicates that the film was shot on a $21 million budget, the largest production budget ever for Malpaso. Another source indicates that over $20 million was spent on special effects.
