Final Fantasy Tactics is a 1997 tactical role-playing game developed and published by Square for the PlayStation. It was released in Japan in June 1997 and in North America in January 1998 by Sony Computer Entertainment. It is the first game of the Tactics sub-series within the Final Fantasy franchise, and the first entry set in the fictional world later known as Ivalice. The story follows Ramza Beoulve, a highborn cadet placed in the middle of a military conflict known as The Lion War, where two opposing noble factions are coveting the throne of the kingdom.

Production was begun in 1995 by Yasumi Matsuno, a newcomer who had created the Ogre Battle series at Quest Corporation. Matsuno's wish was for an accessible tactical game with a storyline focusing on class-based conflict and the rewriting of history. Matsuno acted as director and writer, Final Fantasy creator Hironobu Sakaguchi was producer, and the battles were designed by Hiroyuki Ito. Multiple other staff members were veterans of the Ogre Battle series, including artists Hiroshi Minagawa and Akihiko Yoshida, and composers Hitoshi Sakimoto and Masaharu Iwata. The game received critical acclaim and has become a cult classic since its release. It sold over one million units in Japan during 1997, and over 2.4 million worldwide by August 2011. It has been cited as one of the greatest video games of all time.

The world of Ivalice became the setting for multiple other titles, including other Tactics games, and the 2006 mainline entry Final Fantasy XII. An enhanced port of the game, Final Fantasy Tactics: The War of the Lions, was released in 2007 as part of the Ivalice Alliance project. An expanded remaster for eighth and ninth generation consoles and Windows, subtitled The Ivalice Chronicles, was released on September 30, 2025.

Final Fantasy Tactics is a tactical role-playing game in which players follow the story of protagonist Ramza Beoulve. The game features two modes of play: battles and the world map. Battles take place on three-dimensional, isometric fields. Characters move on a battlefield composed of square tiles; movement and action ranges are determined by the character's statistics and job class. The battlefield also factors in elements such as terrain and weather to determine strategic advantages and disadvantages during clashes. Battles are turn-based; a unit may act when its Charge Time (CT) reaches 100 and increased once every CT unit (a measure of time in battles) by an amount equal to the unit's speed statistic. During battle, whenever a unit performs an action successfully, it gains experience points (EXP) and job points (JP). Actions can include magical attacks, physical attacks, or using an item. Hit points (HP) of enemy units are also visible to the player (except in the case of certain bosses), allowing the player to know how much damage they still have to inflict on a particular unit.

In the world map, the player moves on predefined paths connecting the towns and battle points. When the character icon is over a town, a menu can be opened with several options: "Bar" for taking sidequest job offers, "Shop" for buying supplies and equipment, and "Soldier Office" for recruiting new characters. Later in the game, some towns contain "Fur Shops" for obtaining items by way of poaching monsters. Random battles happen in pre-set locations on the map, marked in green. Passing over one of these spots may result in a random encounter.

Tactics features a character class system, which allows players to customize characters into various roles. The game makes extensive use of most of the original character classes seen in earlier Final Fantasy games, including Summoners, Wizards (Black Mages), Priests (White Mages), Monks, Lancers (Dragoons), and Thieves. New recruits start out as either a Squire or a Chemist, the base classes for warrior and magician jobs, respectively. The game features twenty jobs accessible by normal characters.

The JP rewarded in battle are used to learn new abilities within each job class. Accumulating enough JP results in a job level up; new jobs are unlocked by attaining a certain level in the current job class (for instance, to become a Priest or Wizard, the unit must first attain Job Level 2 as a Chemist), which also allows the character to gain more JP in that class in battles. Once all the abilities of a job class have been learned, the class is "Mastered". A soldier in a specific Job always has its innate skill equipped (Wizards always have "Black Magic", Knights always have "Battle Skill") but a second job-skill slot and several other ability slots (Reaction, Support, and Movement) can be filled with any skill the particular soldier has learned.

The story takes place in the kingdom of Ivalice, inspired by the Middle Ages. The kingdom is located in a peninsula surrounded by sea on the north, west and south, with a headland south of the landmass. It is heavily populated by human beings, although intelligent monsters can be found living in less populated areas. Magic is predominant in the land, although ruins and artifacts indicated that the past populace had relied on machinery, such as airships and robots. Ivalice's neighbors are the kingdom of Ordalia in the east and Romanda, a military nation to the north. While the three nations share common royal bloodlines, major wars have taken place between them. An influential religious institution known as the Glabados Church heads the dominant faith, centering around a religious figure known as Saint Ajora.
