Five Nights at Freddy's 3 is a 2015 indie point-and-click survival horror video game designed by Scott Cawthon, and the third entry in the Five Nights at Freddy's series. The game was released on Steam on March 2, 2015, for Android devices on March 7, 2015, and for iOS on March 12, 2015.

Gameplay deviates from the previous games in the series slightly. In keeping with the first two installments, players are once again tasked with surviving a week of night shifts, the difference this time being that there is only a single animatronic present (though some of the animatronics from earlier in the series return in the form of phantoms, which are unable to harm the player directly, but can impede efforts to survive during the night shifts). The game takes place in a horror attraction, which is referred to in-game as residing on the site of a former Fazbear Entertainment restaurant. The attraction aims to capitalize on the previous incidents that occurred at the various restaurants formerly operated by Fazbear Entertainment. Players must monitor two different camera systems (security cameras within the building, and cameras within the ventilation system) and three subsystems; Audio (which is used to lure the animatronic away from the player's Office), Security Cameras (used to observe and track the animatronic's position), and Ventilation (which the player is told must be kept running in order to avoid seeing hallucinations during the shift.) The subsystems can, and will, fail periodically, and must be rebooted immediately to avoid undesirable effects.

The game consists of five nights, increasing in difficulty, and completing all five unlocks an even more challenging "Nightmare" night. Between nights, the player is able to play one of several low-resolution minigames as the animatronics from the first game, with several vague hints scattered around the minigames for players to decipher. Players who decipher these hints will unlock the "good ending", as well as bonus content such as additional minigames and a cheat menu
