Atheist groups are organizations that promote atheism, which is the lack of belief in gods or deities. These groups often focus on advocating for secularism, scientific reasoning, and critical thinking. They may also work to support the rights of non-believers and challenge religious influence in public policy and education. Many atheist groups engage in community service, educational outreach, and social events to foster a sense of belonging among non-believers. Some well-known organizations include the American Atheists and the Freedom From Religion Foundation. These groups aim to create a supportive environment for individuals who identify as atheists or are questioning their beliefs.
