The Kenya National Association of Probation Officers (KNAPO) was founded in 1976 by serving Probation Officers in Kenya and was registered by the Registrar of Societies as an association. Since its inception, KNAPO has continued to grow as a professional and welfare association for all practicing and retired Probation Officers.

The association has 11 branches all over the Republic of Kenya and has the National Secretariat based in the capital city of Nairobi. As a nonprofit organization with commitment to professionalism, KNAPO's code of ethics governs the conduct and operations of Probation Officers in Kenya.
