The rapid pace of technological change has significantly transformed the librarianship profession, impacting the required competencies for professionals working in library and information services (LIS). As new roles emerge within academic libraries, librarians need to assess their current knowledge and skills as well as identify additional knowledge and skills needed to adapt to evolving roles and responsibilities. This paper reports findings of a study conducted at two university libraries in South Africa. The objective of the study was to identify the competencies necessary for academic librarians in providing research data management services (RDM). While previous studies have explored the knowledge and skills required for academic librarians in Southern Africa and globally, there is a research gap concerning the specific competencies necessary for RDM. This study employed semi-structured interviews with librarians from two selected university libraries, using purposive sampling. The research also included document reviews and content analysis of relevant academic library job advertisements. The study’s findings highlight key competencies such as information and data management practices, repository management, data curation, data collection management, understanding funders’ policies, research Research Data Management Competencies for Academic Libraries: Perspectives from Two Universities in South Africa methods and processes, as well as ICT and digitization skills. The findings also highlight the importance of robust training and selfdevelopment through online courses, webinars, and freely available materials as strategies to support RDM.
