This study evaluates Namibia's maritime security frameworks and their role in facilitating the country's transition to a green economy. Namibia's coastline, rich in marine resources, presents both opportunities and challenges for sustainable development. This study investigates the effectiveness of current ocean governance and conservation strategies in promoting sustainability, identifies gaps and opportunities in maritime security, and proposes policy recommendations for enhancing sustainable ocean management. Grounded in global sustainability principles, the research aligns Namibia's maritime security agenda with Sustainable Development Goals (SDGs) 14 (life below water) and 16 (peace, justice, and strong institutions). A qualitative research approach was employed, combining policy document analysis with stakeholder consultations conducted through semi-structured interviews. This methodological design enabled the collection of nuanced insights into policy frameworks, institutional capacities, and stakeholder perspectives on maritime security and sustainable ocean governance. The findings reveal the critical role of effective maritime security and governance in advancing Namibia’s green economy aspirations. This study contributes to global discussions on operationalizing sustainable ocean principles by addressing socio-economic and environmental dimensions of maritime security. Keywords: maritime security, sustainable oceans, green economy, ocean governance, conservation strategies, Namibia.
