The RPGA, alternatively known as the Role Playing Game Association and the RPGA Network, is a subsidiary of Wizards of the Coast that organized Star Wars tournament adventure scenarios under both the West End Games d6 and the later Wizards of the Coast d20 RPG systems. Founded in November 1980 by Frank Mentzer of TSR, Wizards of the Coast acquired the RPGA when they purchased TSR in 1997.
