Torg is a cinematic cross-genre tabletop role-playing game created by Greg Gorden and Bill Slavicsek, with art by Daniel Horne. It was first published by West End Games (WEG) in 1990. Game resolution uses a single twenty-sided die, drama cards and a logarithmic results table, which later formed the basis for WEG's 1992 sci-fi RPG Shatterzone and 1994 universal RPG Masterbook. WEG produced over fifty supplements, novels and comics for the first edition. A revised and expanded core rule book was produced in 2005, with a single adventure. After WEG closed in 2010, Torg was sold to Ulisses Spiele, who, after a successful crowdfunding campaign, published a new edition called Torg: Eternity in 2018.

Torg is set on Earth during an alien invasion, and players play archetypal heroes from differing genres. The game's title, Torg, refers to an in-game title that individual leaders of the invasion strive to achieve.
