Far Cry 5 is a 2018 first-person action-adventure shooter game, developed by Ubisoft Montreal and Ubisoft Toronto and published by Ubisoft. It is the successor to 2014's Far Cry 4, and the fifth main installment in the Far Cry series. Set in Hope County, a fictional region of Montana, United States, the game revolves around the Project at Eden's Gate, a doomsday cult that has taken over the county at the command of its charismatic and powerful leader, Joseph Seed. Players control an unnamed junior deputy sheriff who becomes trapped in Hope County and must work alongside various resistance factions to liberate the region from the despotic rule of the Seeds and Eden's Gate. Gameplay focuses on combat and exploration; players battle enemy soldiers and dangerous wildlife using a wide array of weapons. The game features many elements found in role-playing games, such as a branching storyline and side quests. The game also features a map editor, a co-operative multiplayer mode, and a competitive multiplayer mode.

Announced in early 2017, development on Far Cry 5 was extensive. The team explored several concepts before settling on an American location. The game was heavily inspired by several socio-political events in modern history, such as the Cold War and the September 11 attacks. The development team sought to capture the despondent social climate after the events and re-purpose it for the game. Developed and published solely by Ubisoft, its competitive multiplayer mode was also created in-house, with the company's worldwide studios gaining more creative input for Far Cry 5.

Far Cry 5 was released worldwide for Microsoft Windows, PlayStation 4 and Xbox One in March 2018. It received mostly positive reviews, although it was the subject of controversy after being announced alongside a period of heightened political conflicts. Critics praised the open world design, visuals, gameplay and soundtrack but directed criticisms towards its story and some of the characters. The game was a commercial success and became the fastest-selling title in the franchise, grossing over $310 million in its first week of sales. Several releases of downloadable content were subsequently published. A spin-off title and sequel to the narrative, Far Cry New Dawn, was released in February 2019. A successor, Far Cry 6, was released in October 2021
