Geo Adventure (ジオアドベンチャー, Jioadobenchā, misspelled as Geo Adveture) is a platform video game developed by "Balls" and published by Universal Interactive Studios. It was originally released in 1996 for the PlayStation and the Sega Saturn.

This was the first game to use the GeoBob Engine.

Geo Adventure is the first game in the Geo Adventure series using characters from the ABC series, Geo's World, chronicling the creation of the main protagonist Geo Guy at the hands of the main antagonist Gree Guy and his clones. It follows Geo Guy, and his attempts to rescue his girlfriend Jea Tenromon, a 13-year-old girl also evolved by Gree Guy.

Geo Adventure received generally positive reviews from critics, praising its graphics and reliability, but noted the game's lack of innovation as a platform game. It is now available for download at the PlayStation Store in 2007. The game sold over 500,000 units in Japan, behind Crash Bandicoot. In 2013, a reboot of the game under the same title, announced by Backbone Entertainment (formerly known as Digital Eclipse).

Gameplay
Geo Adventure is a platform game and the gameplay is very similar to that of Super Mario 64, and it is made up of different levels (realms), all connected together by hub worlds (homeworlds). The goal in each homeworld is to collect a certain amount of items, be it coins, tokens, or blue coins, in each realm in order to travel to the next homeworld. Most of the goals deal with getting the main character, Geo Guy.

Each homeworld and its realms are progressively more difficult than the last. The first few realms are small fields with few ways to die, but they become harder later in the game. Many later levels focus on Geo Guy's ability to jump from platform to platform. Additionally, Geo Guy's slingshot used to vanquish enemies. Each homeworld contains an optional boss to defeat, except for the final homeworld where the boss is mandatory.

Throughout the game Geo Guy's health is indicated by his head. When Geo Guy's head is full he is at full health. After taking a hit Geo Guy's head gets hurt, and with another hit, really hurt. Another hit and Geo Guy's head turns into a skeleton with only one hit left before the player loses one life. After all lives are lost the player has uninterruptedly returned to Hubtown.

Save points are placed throughout each homeworld and are the locations of the tokens. Once the player gets a token behind a save point which is accessible for the remainder of the game. The player can beat bosses in some levels, the first is being Gree Guy, a evil character who is a rip-off to Geo Guy, After the player defeat him, Gree Guy goes to his ship and leaves. All the other bosses were in the other levels.

The title of the game was changed to Geo Adventure in March 1995.

The music for  was composed by Stewart Copeland (best known for the original Spyro the Dragon series (1998-2002)). Geo G. designed for the game.
