Abstract: Community Health Nurses (CHNs) play a pivotal role in strengthening primary healthcare systems and achieving universal health coverage, particularly in low- and middle-income countries. Rapid epidemiological transitions, emerging public health threats, technological advancements, and evolving community needs have expanded the scope and complexity of community health nursing practice. In this context, capacity building through continuing education has emerged as a critical strategy to enhance nurses’ competencies, professional confidence, and service delivery outcomes. This review article examines the concept of capacity building among community health nurses, emphasizing the role of continuing education in improving knowledge, skills, attitudes, and leadership capabilities. It explores global and national perspectives, theoretical underpinnings, educational strategies, barriers and facilitators, and the impact of continuing education on nursing practice and community health outcomes. The article further highlights policy implications and future directions for strengthening continuing education frameworks to support sustainable capacity building of community health nurses. Strengthening continuing education systems is essential not only for professional development but also for improving quality, equity, and responsiveness of community-based healthcare services.
