Abstract The successful implementation of Sustainable Development Goals (SDGs) in Sub-Saharan Africa depends not only on policy formulation but also on effective public awareness, stakeholder engagement, and participatory communication. This study examines the role of public relations (PR) strategies in enhancing SDG awareness and fostering active citizen participation across the region. Using a qualitative, exploratory approach, data were collected through semi-structured interviews with PR practitioners, government communication officers, media professionals, and community leaders, complemented by document analysis of development communication campaigns. Findings reveal that media relations, community engagement, advocacy, and digital communication are central to raising awareness and building trust among diverse stakeholders. Integrated, culturally adapted, and participatory PR approaches were found to be most effective in promoting comprehension, local ownership, and behavioural change. Anchored on the Excellence Theory of Public Relations, Stakeholder Theory, and the Two-Way Symmetrical Communication Model, the study concludes that strategic public relations is a critical mechanism for bridging the SDG awareness gap, enhancing stakeholder collaboration, and improving the sustainability of development initiatives. Recommendations include adopting multi-platform communication strategies, prioritizing community engagement, leveraging digital tools, and strengthening capacity and coordination among development actors.
