Pitfall! is a platform video game designed by David Crane for the Atari 2600 and released by Activision in 1982. The player controls Pitfall Harry and is tasked with collecting all the treasures in a jungle within 20 minutes. The world consists of 255 screens which are horizontally connected in a flip screen manner. Each screen has one or more hazards: quicksand, tarpits, rolling logs, crocodiles, snakes, scorpions, campfires, and swinging vines.

Pitfall! received positive reviews upon release and is now considered one of the greatest video games ever made. It is one of the best-selling games on the Atari 2600, with over four million copies sold. It was the top video game on the Billboard charts for more than a year, and it helped define the flip-screen platform game genre. Across all versions, the game sold over 5 million copies worldwide.

The game was followed by several sequels, beginning with Pitfall II: Lost Caverns, which was also developed by Crane; it was released for the Atari 2600 in 1984.
