Tekken 3 is a fighting game, the third entry in the Tekken series. It was released to the arcades in 1997, before being ported to the PlayStation in 1998. The arcade version of the game was released in 2005 for the PlayStation 2 as part of Tekken 5's Arcade History mode. The game was also re-released as part of Sony's PlayStation Classic.

Tekken 3 features a largely new cast of characters, including the debut of several now-staple characters such as Jin Kazama, Ling Xiaoyu, Bryan Fury, Eddy Gordo, and Hwoarang, with a total of twenty-three characters. The home version includes a new beat 'em up mode called Tekken Force, and the bonus Tekken Ball mode.

The game was a major hit for both arcades and consoles, selling 35,000 arcade units and more than 8 million PlayStation copies worldwide, making Tekken 3 the fifth best-selling PlayStation game. Since its release, Tekken 3 has been cited as one of the greatest video games of all time. It was followed by Tekken Tag Tournament, a non-canon installment in 1999. The direct sequel, Tekken 4, was released in 2001.

Tekken 3 maintains the same core fighting system and concept as its predecessors. Three-dimensional movement is insignificant in previous Tekken games (aside from some characters having unique sidesteps and dodging maneuvers), but Tekken 3 adds emphasis on the third axis by allowing characters to sidestep in or out of the background. Fighters now jump more reasonable heights than in the previous games, making them less overwhelming and putting more use to sidestep dodges, as jumping can no longer dodge every ground attack. Reversals, introduced for some characters in Tekken 2, were now available to all characters. New improvements include quicker recoveries from knockdowns, more escapes from tackles and stuns, more moves with juggling enabled, and newly created combo throws.

Tekken 3 introduces a beat 'em up minigame called "Tekken Force", which pits the player in various stages against enemies in a side-scrolling fashion. The concept was expanded on in a minigame for Tekken 4, and succeeded by the Devil Within campaign mode in Tekken 5. Another minigame is known as "Tekken Ball", similar to beach volleyball, where the player must hit the ball with a powerful attack to pulverize the opponent, or cause them penalty damage by letting the ball fall into the opponent's territory.
