The United Atheist Alliance (UAA) is an organization founded in the mid-21st century in an alternate timeline. The UAA believe that their answer to the great question of what atheists should call themselves makes more sense than the rival groups'. Cartman appears to work with the Alliance for the most part despite being unfrozen by the Unified Atheist League (UAL) and spending a lot of off screen time with the Allied Atheist Alliance (AAA).
