Microfinance programmes have been implemented in Nairobi slums to support youth entrepreneurship and livelihoods, aiming to address economic challenges faced by marginalized communities. Qualitative research methods were employed, including semi-structured interviews with participants (n=30) and document analysis of programme records. Data collection was conducted between January and March . Microfinance programmes showed a significant increase in business start-ups among youth participants, particularly in sectors such as agriculture and retail, contributing to local economic diversification. The study concludes that microfinance programmes have effectively facilitated the growth of small businesses in Nairobi slums, fostering entrepreneurial skills and community resilience. Future research should explore longer-term impacts and scalability of these programmes. Policy recommendations suggest integrating financial literacy training into programme design to enhance sustainability. Microfinance, youth entrepreneurship, Nairobi slums, qualitative evaluation
