Jayne Wanjiru Kihara (born 1960) is a Kenyan politician and long-serving Member of Parliament for Naivasha Constituency in Nakuru County, currently representing the United Democratic Alliance (UDA). She first entered Parliament in a 2003 by-election on a NARC ticket, succeeding her late husband, former Naivasha MP Paul Samuel Kihara, and served until 2007 before making a comeback in 2017 and winning re-election in 2022, giving her three non-consecutive terms in the National Assembly. In the 13th Parliament she is a senior UDA legislator and an active member of key committees, having served on the Departmental Committee on Lands and the National Cohesion and Equal Opportunity Committee, and more recently on the Members’ Services and Facilities Committee, where she contributes to oversight of land governance, cohesion policies and internal parliamentary welfare. She has also been a visible participant in major national debates, including supporting the passage of the 2023 and 2024 Finance Bills, and has featured prominently in politically charged discussions around land ownership and constituency bursary management in Naivasha. Kihara’s political career is rooted in a long trajectory through Kenya’s civil service and corporate sector. She attended Riamukurue Primary School, Githunguri Girls Secondary School and Cathedral Secretarial College, later obtaining business-education certifications from the East African Examinations Council. She began her working life as a shorthand typist at the Ministry of Labour in the late 1970s before moving into the private sector as a personal assistant at Gailey & Roberts and Philip Morris Services Inc., and then rising through the ranks at Orbit Chemicals Industries, where she held roles including transport manager and credit controller between the mid-1980s and early 2000s. That blend of administrative experience, exposure to industry and a personal political story shaped by succession after her husband’s death has informed her brand as a firm, grassroots-oriented representative for Naivasha, combining constituency development work with a loyal alignment to the Rift Valley wing of Kenya’s ruling coalition.
