Europa Barbarorum (Latin: Europe of the Barbarians), or EB, is a modification of the PC game Rome: Total War (RTW) based on the desire to provide Rome: Total War players with a more historically accurate game experience.

The basic gameplay mechanics of the original game remain the same. The player controls an empire with the goal of conquering as much territory as possible and eliminating rival factions, which are controlled by the computer, or AI. The main campaign is split between two gameplay modes: a turn-based strategy map for moving whole armies and managing the empire, and a real-time battle map for fighting battles on the ground between two or more armies. The two game modes are linked, with success or failure in one game mode influencing the chances of success or failure in the other.

Although set in a similar historical period and geographical area to the unmodified game (covering a timespan of 272 BC to 14 AD, compared to the original game's 270 BC to 14 AD),Europa Barbarorum is a total conversion modification as it replaces all the aspects of the original Rome: Total War game that can be replaced, such as unit models, statistics and the musical score. The modification has received favourable reviews in a number of computer gaming magazines.PC Gamer magazine ranks Europa Barbarorum as the best mod for any of the seven Total War games currently released for the PC.
