Atheist associations are organizations that cater to the interests and beliefs of non-believers. The term "atheist" has garnered negative connotations in some societies, which has led to the creation of alternative phrases including "freethinker" and "humanist." These groups of individuals share common views, ideologies, and objectives with secular groups, non-religious groups, and skeptic organizations. Some of the popular synonyms for "atheist associations" are non-theistic associations, non-believer communities, and rationalist societies. The members of these associations often come together to discuss matters concerning science, philosophy, and politics with the aim of promoting reason, scientific literacy, and ethical behavior.
