Honor of Kings (simplified Chinese: 王者荣耀; traditional Chinese: 王者榮耀; pinyin: Wángzhě Róngyào, unofficially translated as King's Glory, or alternatively transliterated as Wangzhe Rongyao) is a multiplayer online battle arena (MOBA) video game developed by TiMi Studio Group and published by Tencent Games for iOS, HarmonyOS NEXT, and Android.

The game was first released in mainland China on 25 October 2015. In October 2016, an international adaptation, Arena of Valor, was released, utilizing the same game engine but altering the user interfaces and heroes to accommodate the Western market. As of November 2020, Honor of Kings had over 100 million daily active players, making it one of the most popular games in the world. It is the highest-grossing mobile game of all time and one of the most downloaded apps globally.

In June 2022, Level Infinite, the publisher of Arena of Valor, announced that Honor of Kings would be released globally through a separate version by the end of 2022. In May 2024, the worldwide launch of the global version was announced for 20 June 2024, following pre-releases in Brazil and Turkey as well as countries in the Middle East and North Africa, South Asia, and the Commonwealth of Independent States. Honor of Kings was the highest-grossing mobile game in the world in 2024, with $2.6 billion gross.

Honor of Kings is a quick-match (15–20 minutes) mobile multiplayer online battle arena (MOBA) game. Either a Tencent QQ account or a WeChat account is required to play the game. Following an update on 24 September 2020, a player can add friends and invite people from different platforms to guilds.

Honor of Kings was the second-highest earning mobile game worldwide for February 2021, with $218.5 million in gross revenue, which represented 57.2% year-over-year growth from February 2020. About 95.6% of Honor of Kings' revenue was from China, followed by 1.6% from Thailand.

Honor of Kings is a multiplayer online battle arena (MOBA) game in which the player controls a character with unique abilities and competes to defeat non-player characters and opponents to gain experience points and gold. With experience points, players can unlock their characters' abilities or further augment the power of their existing abilities. The highest level that each hero can reach in the game is level 15. Each level up not only improves the attribute values of the character players control but also gives them a skill point to upgrade their skills. There is a character called "Jiang Ziya" in the game who can use his unique "Fengshen" skill to remove the level limit for himself and another character. However, after level 15, he can only improve the attribute values of the character. Gold can be used to purchase items at the shop that uniquely change specific attributes of the character.

To win a game, players need to knock down the enemy's defensive structures, called turrets. Victory is achieved by destroying the opponent's base crystal, located within the enemy team's base. Specific gameplay mechanics vary depending on the game mode chosen.

Experience and gold are also earned across matches and applied to player accounts. Accounts start at level 1, with level 30 being the maximum level. In the global release, however, the level cap is removed. Upon leveling up, users receive bonus in-game awards. Leveling up also unlocks certain summoners' abilities that can be applied to every hero the summoner uses. Gold can be used for a variety of purposes, such as purchasing new heroes.
