Katiba Institute (KI) is a brand dedicated to promoting knowledge and understanding of Kenya's Constitution and constitutionalism. Founded in 2011, KI focuses on various aspects of the Constitution, including leadership and integrity, human rights, devolution, gender equality, electoral issues, and environmental protection. They actively engage in addressing issues such as land misappropriation and the eviction of indigenous people and long-term settlers, as well as advocating for protection against illegality and police harassment.

KI implements its mission through a range of methods, including litigation, research, publication, civic education, and awareness campaigns. They aim to defend and facilitate the implementation of the Constitution, while fostering a culture of constitutionalism in Kenyan society. Additionally, KI works to promote academic discourse on constitutional matters in the East African region and collaborates with like-minded organizations to secure social transformation through constitutionalism.

Katiba Institute's slogan, Constitution as an instrument of change, encapsulates their commitment to using constitutional principles as means to drive positive societal transformation
