Fire Emblem is a fantasy tactical role-playing game franchise developed by Intelligent Systems and published by Nintendo. First produced and published for the Nintendo Entertainment System in 1990, the series currently consists of seventeen core entries and five spinoffs. Gameplay revolves around the tactical movement and actions of characters across grid-based battlefields, while incorporating a story and characters similar to traditional role-playing video games.

A notable aspect of gameplay is the permanent death of characters in battle, removing them from the rest of the game when they are defeated. In newer games, from Fire Emblem: New Mystery of the Emblem onwards, players get to choose between Classic Mode, in which fallen characters remain dead, or Casual Mode, in which fallen characters are revived for the next battle. The series title refers to the "Fire Emblem", a recurring element in the series that is usually portrayed as a royal weapon or shield representing the power of war and dragons. The development of the first game began as a dōjin project by Shouzou Kaga and three other developers. Its success prompted the development of further games in the series. Kaga headed the development of each entry until the release of Thracia 776, when he left Intelligent Systems and founded his game studio to develop Tear Ring Saga.

No games in the series were released outside of Japan until two characters, Marth and Roy, were included as playable characters in the 2001 fighting game Super Smash Bros. Melee. Their popularity, as well as the international success of the similarly turn-based Advance Wars, eventually convinced Nintendo to release future games in Western territories, starting with the seventh game The Blazing Blade under the title Fire Emblem in 2003. Many games in the series sold well, although sales suffered a decline during the 2000s. This resulted in the series' near-cancellation, a fate that was reversed with the unprecedented critical and commercial success of Fire Emblem Awakening (2012). Individual entries have generally been praised, the series as a whole has been lauded for its gameplay, and it is frequently cited as the seminal series in the tactical role-playing genre, codifying various gameplay elements that would come to define the genre. Characters from across the series have also been included in crossovers with other video game franchises, including the aforementioned Super Smash Bros. series.
