Effective organisational leadership remains a critical determinant of sustainable service delivery within South Africa’s local government sphere, particularly in Mpumalanga Province’s municipalities. Persistent governance failures, administrative instability, financial mismanagement, political interference, and declining public trust continue to undermine municipalities’ ability to deliver essential services efficiently and equitably. This literature review critically examines the relationship between organisational leadership and municipal service delivery, with particular emphasis on the leadership challenges facing local municipalities in Mpumalanga Province. The study draws on contemporary scholarly literature, government reports, policy documents, and institutional publications from sources such as the South African Local Government Association (SALGA), the Local Government Sector Education and Training Authority (LGSETA), National Treasury, and the Auditor-General South Africa. A qualitative desktop research methodology was employed to analyse literature published primarily within the last decade. The review identifies several leadership deficiencies affecting municipal performance, including inadequate strategic leadership capacity, weak accountability systems, political-administrative interference, ineffective communication, limited stakeholder engagement, poor financial management, and insufficient leadership development initiatives. The findings further reveal that ineffective leadership contributes significantly to service delivery protests, community dissatisfaction, governance instability, and institutional decline within municipalities. The study argues that strengthening leadership competencies, promoting ethical governance, enhancing accountability mechanisms, and fostering participatory governance are essential for improving municipal performance and developmental outcomes. The article contributes to ongoing debates on local governance reform by proposing leadership-centred interventions to improve service delivery effectiveness and restore public confidence in Mpumalanga municipalities.
