Who are we?

Our mission

Our mission is to promote the growth and interaction of atheists in Kenya.
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 broad worldview which describes a number of shades of opinion, but the core set of beliefs and values can be summarised as follows:

A humanist …

1. Trusts to the scientific method when it comes to understanding how the universe works and rejects the idea of the supernatural (and is therefore an atheist or agnostic)

2. Makes their ethical decisions based on reason, empathy, and a concern for human beings and other sentient animals
believes that, in the absence of an afterlife and any discernible purpose to the universe, human beings can act to give their own lives meaning by seeking happiness in this life and helping others to do the same.

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.

Legal Redress

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.
