Oscar Muriu (N/A–N/A) is a Kenyan preacher and the Senior Pastor of Nairobi Chapel, a thriving evangelical church in Nairobi, Kenya, where he has served since 1991. Born and raised in Kenya, Muriu dedicated his life to Christ in 1983 after a period of skepticism during his student years, which included studying for a B.Sc. in Zoology at the University of Delhi in India. He later earned an M.Div. from the Nairobi Evangelical Graduate School of Theology (now Africa International University). Under his leadership, Nairobi Chapel grew from a small congregation of 20 people to a network of over 90 churches across Kenya and Africa, including Rwanda, Botswana, Malawi, Zambia, Ghana, Liberia, and Ethiopia, with more than 18,000 weekly worshippers. He is married to Beatrice (Bea), and they have four daughters: Chiru, Chiku, Wanja, and Janelle. Muriu’s preaching career is defined by his passion for church planting and raising African leaders for global Christianity, a mission he pursues through Nairobi Chapel’s aggressive church-planting strategy—aiming for 300 churches by 2020—and initiatives like training over 500 interns. His sermons, often emphasizing leadership, discipleship, and the transformative power of the gospel, have been featured at international events such as Urbana (2006, 2009), the Willow Creek Global Leadership Summit, and The Gospel Coalition conferences. A key figure in the Lausanne Movement, he advocates for unity and mission among diverse churches. Based in Nairobi, Muriu continues to lead Nairobi Chapel, leaving a legacy as a visionary preacher committed to multiplying gospel impact across generations and continents.
