ABSTRACT This paper’s purpose is to systematically analyse and understand the complexity of strategic-level stakeholder management within defence. Empirical data was collected via a rigorous systematic literature review of 10,369 manuscripts contained within the Web of Science, with 206 A1 studies constituting the final paper set. This was followed by bibliometric and maturity analysis leading to extraction, synthesis and integration of insights. In doing so, knowledge on defence stakeholders is consolidated beyond the traditional field of political science. The results illuminate aspects of stakeholder network complexity, including stakeholders that need to be better understood and holistic frameworks important for contextualising initiatives. Further, the need to move beyond bilaterally-focussed relationships towards the consideration of the larger ecosystem is emphasized. Finally, managers are encouraged to internalise engagement capabilities, able to continuously balance diverse stakeholder cultures and interests. Thereby, contributions are made towards the development of descriptive, instrumental and normative stakeholder theory within defence.
