Turok: Dinosaur Hunter is a first-person shooter video game developed by Iguana Entertainment and published by Acclaim Entertainment. It was released in 1997 in North America and Europe for the Nintendo 64 and Microsoft Windows, and is an adaptation of the comic book series of the same name from Valiant Comics. The player controls Turok, a Native American warrior who must stop the evil Campaigner from conquering the universe with an ancient and powerful weapon.

As Acclaim's first title for the Nintendo 64, Turok was part of a strategy to develop games internally and license merchandise. Acclaim acquired the rights to Turok when it purchased Valiant Comics in 1994, renaming it Acclaim Comics. Suffering from cash flow problems and falling sales, Acclaim came to rely on Turok as its best hope for a financial turnaround. Iguana pushed the Nintendo 64's graphics capabilities to its limits, and were forced to compress or cut elements to fit the game on its 8 megabyte cartridge. Bugs delayed the game's release from September 1996 to January 1997.

Critical reception of Turok was highly positive. Becoming one of the most popular games for the console on release, Turok won praise for its graphics and evolution of the genre. Complaints centered on graphical slowdowns caused by multiple enemies appearing onscreen and occasionally awkward controls. The game sold 1.5 million copies and boosted sales of the Nintendo 64. Turok spawned a video game franchise that includes a direct sequel, titled Turok 2: Seeds of Evil, in 1998, and a prequel, Turok: Evolution, in 2002. A remastered version of the game by Nightdive Studios was released through digital distribution for Microsoft Windows in 2015, followed by an OS X release in 2016, Xbox One and Linux releases in 2018, a Nintendo Switch release in 2019, a PlayStation 4 release in 2021, and PlayStation 5 and Xbox Series X/S releases in 2025. The original game was also re-released on the Nintendo Classics service via the Mature 17+ app in June 2024.

Played from a first person perspective, the 3D graphics and style of play combine elements of the run-and-gun video game Doom with exploration mechanics of Tomb Raider. Players begin the game in a central hub level, which contains portals to seven other stages. The player must find keys scattered across the stages. When enough keys have been inserted into the lock mechanisms of a hub portal, that level is unlocked. Players explore the large, typically jungle-based levels by jumping, swimming, climbing, crawling, and running.

One of the player's main objectives is to find pieces of a relic known as the Chronoscepter; there is one piece on each level. In exploring the levels the player fights various enemies such as poachers, gunmen, indigenous warriors, dinosaurs, demons, and insects. Turok features 13 weapons plus the Chronoscepter, ranging from a knife and bow to high tech weaponry. All weapons except the knife require ammunition, which is dropped by dead enemies or picked up in the levels. Enemies and boss characters have multiple death animations depending on what body region the player shot. Because items dropped by fallen enemies rapidly disappear, players must engage foes from close range.

The player character's health is shown as a number at the bottom of the screen. When the player is at full health, the meter reads 100, while dropping to 0 subtracts one life, and losing the last life ends the game. Gathering "life force" points scattered across the levels increases the player's life count by one for every 100 points accumulated. Players restore health by picking up powerups, which can increase health above full. Players may also gain health points by shooting deer or non-threatening wildlife.

The player assumes control of Tal'Set (Turok), a Native American time-traveling warrior. The mantle of Turok is passed down every generation to the eldest male. Each Turok is charged with protecting the barrier between Earth and the Lost Land, a primitive world where time has no meaning. The Lost Land is inhabited by a variety of creatures, from dinosaurs to aliens. An evil overlord known as the Campaigner seeks an ancient artifact known as the Chronoscepter, a weapon so powerful that it was broken into pieces to prevent it from falling into the wrong hands. The Campaigner plans on using a focusing array to magnify the Chronoscepter's power, destroying the barriers that separate the ages of time and rule the universe. Turok vows to find the Chronoscepter's eight pieces and prevent the Campaigner's schemes.

Turok originally appeared in comics from Western Publishing and Dell Comics in December 1954. Valiant Comics revived the series and published the first issue of their Turok series in 1993. Video game publisher Acclaim Entertainment bought Valiant for $65 million in 1994 and acquired developer Iguana Entertainment for $5 million plus stock a year later, part of a strategy to develop games in-house and make money licensing characters in different entertainment media. Turok was announced in August 1994 as an exclusive title for Nintendo's planned "Ultra 64" console, eventually called the Nintendo 64.
