Avatar Legends: The Roleplaying Game is a fantasy tabletop role-playing game produced by Magpie Games. It is set in the world of the animated television series Avatar: The Last Airbender and The Legend of Korra, and takes place in five different time periods. Players take the roles of martial artists, technological experts, or benders – people who can manipulate one of the four classical elements – who fight for balance in the world while also working towards their own goals and struggling with inner balance, represented by opposing ideals held by a character.

The game is lead designed by Brendan Conway, and is built on the Powered by the Apocalypse framework, chosen for its accessibility while enabling systems around bending and politics. It was financed through a crowdfunding campaign, which raised US$9.53M, overtaking The One Ring Roleplaying Game's second edition and the Dungeons & Dragons book Strongholds & Followers as the highest funded campaigns for tabletop games on Kickstarter. A free quickstart e-book with basic rules was released in July 2021. Pre-orders for the full base game opened on October 12, 2022, with the Digital Edition becoming available on October 26. The Wan Shi Tong's Adventure Guide expansion book also became available on October 26, and the physical versions of both it and the base rulebook were released on January 25, 2023. Additional expansion books are planned for a future release.

The game won the 2023 Gold ENNIE Awards for "Best Rules" and "Best Family Game/Product."

Avatar Legends: The Roleplaying Game is a fantasy tabletop role-playing game set in the world of the animated television series Avatar: The Last Airbender and The Legend of Korra, which is based on historical South Asian, East Asian and Indigenous North American cultures and martial arts. In the setting, some individuals known as benders can manipulate one of the four classical elements – earth, water, air, or fire – but only one person, called the Avatar, can bend all four. Bending is used both as a tool and a weapon, and the elements are each tied to a nation in the setting. Campaigns are set in one of five time periods: Avatar Kyoshi's and Avatar Roku's eras, long before the events of Avatar: The Last Airbender; the hundred-year war era, during the Fire Nation's attacks prior to the beginning of Avatar; Avatar Aang's era, during and after Avatar; and Avatar Korra's era, during the modernizing time of The Legend of Korra. The antagonists of the setting are people with their own goals and desires, rather than monsters that can simply be struck down.

Players create their own characters with the help of playbooks – templates based on archetypes of characters' life experiences, exemplifying different playstyles – and choose between playing as benders, martial artists, or technological savants, all of which are available to any playbook. Led by a gamemaster (GM), players role-play as their characters in one of the five time periods, where they fight for balance in the world, while trying to reach goals they have set out for themselves and struggling with inner balance. This is represented by a balance track, showing a tug-of-war between two opposing ideals a character has, such as confidence versus loyalty. Certain actions and decisions move a counter between the two ideals on the character's track, affecting two related attributes, and when a character is balanced, they have access to a powerful "moment of balance" ability. Characters have four basic attributes – creativity, focus, harmony, and passion – and have differing base abilities based on their playbooks, with the potential to acquire new abilities through a growth mechanic connected to answering questions at the end of play sessions, or through being taught by mentor characters. Storytelling in the game is structured similarly to the television shows, with individual play sessions corresponding to episodes that together form seasons.

Avatar Legends is produced by Magpie Games, by ten full-time staff and several part-time contributors, with Brendan Conway and James Mendez Hodes as lead designers. The team worked together with many other Asian game designers, writers, and consultants to portray the game's setting as authentically as possible. The designers intended the game to be accessible to players of all ages, and sought to capture what they saw as the core of the Avatar franchise: balance, heroism, the power of friendship, growing up in wartime, the responsibility of power, the damaging legacy of colonialism, and empathy in relationships.

The game is designed with the Powered by the Apocalypse framework as a base, which Magpie Games had previously used in games including Masks: A New Generation and Root: The Roleplaying Game; they chose it as they considered it accessible for those new to role-playing games, while allowing for systems around elemental bending and politics. They also appreciated Powered by the Apocalypse's character playbooks, which they focused on archetypes of different lived experiences rather than an "innate characteristic like race or heritage", with the intent of exploring life in a world of colonization and systemic oppression, and encouraging players to role-play characters rather than Asian stereotypes.

In addition to this concern around handling Asian cultural influences on the setting – made somewhat easier by the lack of a direct analogue to white people in the setting, making the Asian characters less othered – one of the production team's major concerns was the portrayal of bending. Magpie Games' CEO Mark Truman thought that although it would have been easy to define bending through a rules-heavy system akin to how magic is handled in Dungeons & Dragons, it would have gone against the ubiquity of bending in the setting. Instead, they chose to let characters have varying competency and training in bending, affecting how well they can manipulate their element, and, taking cues from characters in the television series, let players customize the bending in accordance with their characters' personalities.
