Kingdom Rush is a 2011 tower defense game developed by Ironhide Game Studio and published by Armor Games. In the game's medieval fantasy setting, players take control of a general serving under King Denas of Linirea, who must defend the land from an onslaught of evil monsters. Each level is composed of a number of pre-set roads, which the player can place defensive towers around to fight off the approaching monsters. Slaying enemies gives the player gold, which they can use to buy new towers or upgrade existing ones to improve their capabilities.

Kingdom Rush was developed over the span of six months by the Uruguay-based developer Ironhide Game Studio. The studio was founded in 2010 by Álvaro Azofra, Pablo Realini and Gonzalo Sande, who conceived Kingdom Rush as their first major project after working on a number of minor Flash games. After seeing the success of tower defense games, the three decided to replicate the basic strategy of the genre, combining it with elements of other games they played in their youth.

Kingdom Rush was first released in July 2011 as a free browser game. Versions for iOS devices were released in December 2011, followed by ports to Android in May 2013, and Windows and macOS in January 2014. A later release for Nintendo Switch was published in July 2020, and versions for Xbox One and Xbox Series X/S were released in January 2023. It was a financial success and received generally favorable reviews from critics, who praised the graphics and tower upgrades, with many considering it a standout tower defense game. After release, Ironhide Game Studio supported Kingdom Rush with a number of free content updates and expansions. The game's success incited plans to grow the video game industry of Uruguay and inspired Ironhide Game Studio to produce related media.
