Unreal Tournament 3 (UT3) is a first-person shooter and online multiplayer video game by Epic Games and is the next installment of the Unreal series after Unreal Tournament 2004. It is published by Midway Games and was released worldwide for Windows in November 2007.

Unreal Tournament 3 is actually the fourth game in the Unreal Tournament series, but the eighth Unreal game, but has been numbered in terms of the engine it runs on. The original Unreal Tournament uses the original Unreal Engine, while UT2003 and UT2004 use the Unreal Engine 2; therefore they are considered as the same generation. UT3 is subsequently part of the third generation, because it runs on the Unreal Engine 3, but also due to the fact that this installment includes a single player campaign mode reminiscent of the Unreal and Unreal 2.
