Need for Speed: Shift is a 2009 racing video game developed by Slightly Mad Studios and published by Electronic Arts for PlayStation 3, Windows, and Xbox 360. A separate version of the game was developed by EA Bright Light and simultaneously released for PlayStation Portable. Two mobile adaptations were developed by IronMonkey Studios for Java-compatible devices and iOS and released in 2009, with the latter version subsequently being made available for several other mobile devices. Need for Speed: Shift is the thirteenth installment in the Need for Speed franchise.

Shift's gameplay focuses on simulation, rather than the arcade racing of previous titles. It was followed by a sequel, Shift 2: Unleashed, in 2011.

As of 2021, Shift is no longer available for purchase in any online stores, and online play was shut down on September 1.

Aimed at a hardcore gamer-style audience, Shift reverts to the sports car racing simulation style of its 2007 predecessor, Need for Speed: ProStreet. Although the gameplay of these two titles are similar, Shift recreates car handling much more realistically than its predecessor, and does not contain a story. Upon starting the career mode, the player performs two laps around the Brands Hatch circuit to determine their skill. Once completed, the player is welcomed to the NFS Live World Series, and must earn stars in races to earn money, and unlock new races and tiers.

G-force plays an important role in the game, as it affects both the player and the AI opponents. The in-car view also returns, making its first appearance in a Need for Speed game since Porsche Unleashed. The in-car view is highly detailed, and it is possible to see the driver changing gears and moving his head to get a better view of the mirror. The crashes affect the player's visuals. While crashing, there is a temporary blur on screen. The sound aspects have detailed car crash sound, as well as a sharp gasp of breath from the driver before a collision.

There are 60+ cars which are divided into 4 tiers. Tier 1 refers to entry-level sports and luxury cars like the Audi TT and Infiniti G35, tier 2 refers to mid-level performance cars like the BMW M3, tier 3 refers to supercars like the Lamborghini Gallardo, and tier 4 refers to hypercars like the Bugatti Veyron and Pagani Zonda R. The car customisation options include cosmetics as well as performance mods and is more in depth than previous titles, affecting aspects such as alignment, aerodynamics, tyres, brakes, differential, and gears. Nitrous is also an option for tuning, but different from previous Need for Speed titles as it is simulated more realistically. There are body kits which affect the aerodynamics and weight reduction. There are visual customisation options like rims, vinyls and paints.

There are 19 tracks in total including real world circuits such as Brands Hatch, Nürburgring Nordschleife, Road America, Spa, Silverstone, Willow Springs, Donington Park, Autopolis, and Laguna Seca.

The PlayStation Portable version of the game offers local, ad hoc multiplayer, with no online multiplayer support.
