Ann Njeri Nderitu (born August 1971) , CBS, is a Kenyan public administrator who has served as a Commissioner of the Independent Electoral and Boundaries Commission (IEBC) since 2025.
She served as the acting registrar of political parties from 2007 to 2018. She left that post in 2018 to become a commissioner with the Commission on Administrative Justice (CAJ) also known as Ombudsman. In 2025, Ann Nderitu was appointed as a Commissioner of the Independent Electoral and Boundaries Commission (IEBC). Before this, she served as the Registrar of Political Parties from 2018 to 2025. As Registrar, her responsibilities included registration and monitoring of political parties, oversight of party governance, regulation and complaints. She also oversaw a project to digitize records and introduced audit and compliance frameworks at the Office of the Registration of Political Parties (ORPP).
During her tenure as Registrar of Political Parties, Nderitu ruled on a dispute involving the Jubilee PartyâÂÂs leadership, a decision that drew criticism from opposition figures who argued that procedural requirements were not followed.
Nderitu handled the case where the Orange Democratic Movement (ODM) party wanted to revoke the party membership of the Malindi MP Aisha Jumwa and her late Mwambweni counterpart Solomon Dori for their dalliance with the then Deputy President William Ruto, who was a member of the rival Jubilee Party. The challenge was dismissed by the RegistrarâÂÂs office on the grounds that the party factions had not complied with the requisite procedural requirements.
Opposition political figures and commentators criticized certain rulings by NderituâÂÂs office as being aligned with the interests of the ruling coalition, though her supporters defended her adherence to the law. During her tenure at the ORPP, initiatives addressed internal democracy in political parties, gender inclusion, and transparency in political party financing.
Nderitu emphasizes the importance of adhering to the law, party constitution, and regulations to ensure her decisions withstand legal scrutiny and align with her responsibilities as the Registrar of political parties.
She attained a Bachelor of Education English and Literature from Moi University in 1995, a Master of Arts in Linguistics from the University of Nairobi in 2007 and a Diploma in Public Administration from the Galilee Institute of Management, Israel in 2018.
