Pitfall: The Mayan Adventure is a 1994 video game developed and published by Activision. A sequel to Activision's classic game Pitfall! for the Atari 2600, the player controls Pitfall Harry, Jr., son of the protagonist of the original game, as he attempts to rescue his father from a Mayan jungle setting.

Activision developed the game in partnership with Redline Games. It was first released for the Super Nintendo Entertainment System, Sega Mega Drive (Sega Genesis) and Mega-CD (Sega CD) in 1994, followed by releases for the Sega 32X, Atari Jaguar, and PC the following year. The PC release was the first commercial release for the recently-debuted Windows 95 operating system. Publisher Majesco Entertainment ported the game for the Game Boy Advance in 2001; a downloadable version appeared on the Nintendo Wii's Virtual Console in 2009.

An extra feature in all versions is the ability to play the original Pitfall! (the Atari 2600 version) after finding a secret doorway within the game. The Sega CD, 32X and Windows ports contained extra (and expanded) levels and other enhancements over the earlier versions. The Windows port was based on the Sega CD version, and made using Kinesoft's Exodus game technology, which was later used to make the Windows port of Earthworm Jim: Special Edition.

On April 13, 2009, the Sega Mega Drive version of Pitfall: The Mayan Adventure was released on the Virtual Console in North America and later in the PAL regions on May 15, 2009 and in Japan on August 25, 2009.
