MotorStorm: Apocalypse is a 2011 racing video game developed by Evolution Studios and published by Sony Computer Entertainment for the PlayStation 3. It is the fourth game in the MotorStorm series and the third for the PlayStation 3. The title was revealed shortly before the beginning of the Electronic Entertainment Expo 2010 on the PlayStation Blog by Evolution Studios on 6 June.

The planned UK release date of MotorStorm: Apocalypse was 16 March 2011, but was delayed by Sony Computer Entertainment UK following the 2011 Tōhoku earthquake and tsunami in Japan. The Australian launch went ahead as planned on 17 March, but Sony announced further shipments of the game to that country were halted in the wake of the disaster. The planned North American release date of 12 April was delayed again by Sony who later confirmed new releases dates of 31 March in the UK and 3 May in North America. The Multiplayer servers were closed on 27 August 2018.

Apocalypse is more story-driven than previous instalments. The events of Apocalypse's MotorStorm Festival are told from the perspective of three participants, labelled Mash "The Rookie", Tyler "The Pro", and Big Dog "The Veteran" by Evolution Studios, with each participant also representing a difficulty level of gameplay. These three participants will each see different parts of the catastrophe unfold over the course of the three-day festival. In the game, racers participate in a three-day festival in a decaying city known as The City, which is the aftermath of a natural disaster. The game is the first in the series to feature an urban setting, as opposed to natural environments. The game has a single-player mode with 40 tracks across three difficulty levels. Each difficulty level focuses on a different racer's story. The game also has a multiplayer mode with support for up to four-player splitscreen races locally, and up to two-player split-screen online. Other online features include 16-player racing, vehicle customization, performance perks, and wagering.

The game takes place in an apocalyptic urban area called The City, based on the West Coast of the United States (in particular California's Bay Area). The game consists of more than 40 tracks that can be altered from active catastrophic earthquakes and tornadoes as well as helicopters crashing through buildings.

New vehicles in the game include supercars, superbikes, hot hatches, muscle cars and choppers. Apocalypse is the first game in the MotorStorm series to focus on an urban setting as opposed to natural environments. The city that the Festival takes place in is enduring the throes of a massive natural disaster, causing the man-made structures in the city to visibly deteriorate. As players race through the tracks, the tracks can change in real-time; bridges can buckle and twist, buildings collapse and rifts open up beneath the vehicles as they drive. Players can also customize their vehicles with vinyls, vehicle parts, and modify the vehicle's handling, boosting and offensive abilities through perks. They are able to create and design their own game rules for online tournaments. A new gameplay element is the addition of "air cooling" one's boost. Similar to driving through cool water in Pacific Rift would speed up the rate of boost cooling, releasing the accelerator over a large jump will also cause the boost temperature gauge to drop quicker.

A new challenge in Apocalypse is the introduction of people who try to interfere in the event. The City houses two factions, known as the Crazies and DuskLite, who vie for survival. The Crazies try to impede the progress of the racers. They loot broken buildings, break into fights on the streets, steal cars and try to slam racers off the road, and attack racers with firearms. A private military company known as DuskLite attempts to enforce order and their involvement creates additional hazards for racers to overcome such as an attack helicopter firing missiles onto the track.

Five new vehicle classes: the supercar, superbike, muscle car, chopper and the hot hatch, are new additions, with the original MotorStorm vehicles, ranging from the MX Motocross bike to the Monster Truck, being included.

Three DLC packs included new vehicles: The first DLC is "Revelation" pack, containing four vehicles that could be either bought entirely or individually.
