Who are we?

The Atheists In Kenya Society is the first and only legally registered atheists organization in Kenya and Eastern Africa. 

AIK was formally registered by the Kenyan government in February 17th, 2016 (View Certificate). Soon afterwards the government suspended our registration and we had to move to the High Court to challenge the suspension of the society. In 2018, the High Court in Kenya found that our suspension was illegal, and consequently quashed the suspension.  We currently have over 1300 registered members, and a following of over 25,000 on our Social Media platforms. 

Our Mission

The mission of the Atheists In Kenya Society is to promote the growth and interaction of atheists in Kenya. 

We welcome atheists, free thinkers, scientists, the LGBTiQ community, gender rights groups, human rights groups, historians and secularists to join us, partner and work with us.

Our Values

At AIK, we are passionate about our work. Our values are the foundation of what we do and how we do it. The key values that guide our work are:

  1. Citizenship: We are mindful of our responsibility to our community and our world, and act purposefully to meet our obligations to both.
  2. Integrity: Our policies and practices support our mission, and we are committed to being a transparent and ethical organization.
  3. Diversity: We encourage and cultivate a climate of awareness, inclusiveness, and respect in everything we do, and we value and celebrate any and all differences among all humans.

Our Philosophical and Ethical Stance

Our philosophical and ethical stance is humanism which emphasizes the value and agency of human beings, individually and collectively, and generally prefers critical thinking and evidence (rationalism, empiricism) over acceptance of dogma or superstition.

Humanism is a progressive philosophy of life that, without theism or other supernatural beliefs, affirms our ability and responsibility to lead ethical lives of personal fulfillment that aspire to the greater good.

Our Quest for Registration

The push for the atheists in Kenya society to be registered by the Kenyan Government began in 2015, when a group of atheists, led by Harrison Mumia issued an ultimatum to Attorney-General Githu Muigai seeking registration.

In a letter addressed to the then Attorney General, Prof. Githu Muigai, the group demanded to be told why the registration of atheists in Kenya society was rejected. The then Deputy Registrar of Societies, Mr Joseph Onyango, had earlier rejected the registration of the atheist society on the grounds that atheism goes against the Constitution of Kenya. After months of back and forth discussions, the Attorney General yielded to demand to have the society registered. The Atheists In Kenya Society was a legally registered society in February 17th, 2016.

Barely two months after the society was registered, the government of Kenya through the office of the attorney general (Prof. Githu Muigai) suspended the society following an uproar from religious groups in April 2016 on grounds that it’s registration was a threat to the peace and good order of the country.

Harrison Mumia moved to the High Court to challenge the suspension of the society. The High Court, in a historic judgement made on February 2018 by Justice Chacha Mwita found that the Attorney General had acted illegally by suspending the society and quashed suspension.

Our Key Objectives


To promote the rational, open and scientific examination of the universe and our place in it.


We believe that science provides the best way to understand the history of the natural world and how the natural world works, with observable physical evidence as the basis of that understanding. 


To advocate that ethics and morality be meaningfully based on rational and humanistic ideals and values


Human thriving is our basis of a solid morality. If your actions lead to the further thriving of humans, then this would be moral. If your actions lead to harmful consequences, then this would be immoral.


To promote skeptical inquiry


We seek to promote critical thinking and the use of reason in examining important issues. We encourage the critical investigation of controversial or extraordinary claims from a responsible, scientific point of view


To provide community for atheists


Through our monthly meetings and our social media groups, we provide an opportunity for atheists to meet and interact.


To organize activities, such as forums for discussion, guest


We organize discussion forums every month where we discuss issues that affect atheists. We invite guest speakers and encourage debate during our meetings.


To foster public acceptance of atheists in Kenya


We promote the acceptance understanding of atheists through education, outreach, and community building.
