Fantasy Games Unlimited, often referred to as just FGU, is a publishing house for both table-top and role-playing games. They have no in-house design teams and rely on submitted material from outside talent.

Founded in 1975 by Scott Bizar, the company's first publications were the wargames Gladiators and Royal Armies of the Hyborean Age. Upon the sudden appearance and massive popularity of Dungeons & Dragons from TSR, the company turned its attentions to role-playing games, seeking out and producing systems created by amateurs and freelancers. Rather than focusing on any one line and supporting it with subsequent supplements, FGU instead produced a continuous stream of new games. In its time, FGU published dozens of different role-playing games, more than any other company.
