TimeSplitters is a series of first person shooter video games, which have a storyline based on time travel. The first two games were published by Eidos. The first, released on the PlayStation 2 as a launch title for the system, while its sequel was also released on Xbox and GameCube, in addition to the PlayStation 2 version. There are currently three games in the series, TimeSplitters, TimeSplitters 2, and TimeSplitters: Future Perfect (published by EA Games).

The original game, TimeSplitters, was developed by the Nottingham based company Free Radical Design and published in 2000 by Eidos. Set over 100 years of past, present and future, TimeSplitters boasts probably the fastest gameplay yet seen in a console FPS, demanding the players keep their wits about them at all times.

The look of the game is substantially more stylised and cartoon-like than most first person shooters, with character models and expressions more closely resembling games such as XIII or Serious Sam than more realistic contemporaries such as Half-Life or Red Faction. This emphasis on often comic book-style character design, many of which represent instantly recognisable parodies of established pop-culture stereotypes (such as the aristocratic English explorer or the suave secret agent) combined with an often surreal and self-mocking style of humour.

The game, and the series as a whole, is notable for the inclusion of a Mapmaker: a simple grid-based level editor. In TimeSplitters, Mapmaker maps may only be used in Arcade mode.

The classic game GoldenEye 007 is often mentioned alongside TimeSplitters because Free Radical Design is a split from Rareware and TimeSplitters is sometimes considered a continuation of the popular FPS style GoldenEye 007 induced
