This study uses the concept of 'organisational power' -- control over the environments in which others interact -- to investigate the structures and lived experience of power among academic associate deans at public, research-intensive universities in the US. Previous research claims that the associate dean role lacks 'legitimate power.' Through in-depth analysis of semi-structured interview data, this study shows that the associate dean role requires a strategic mode of power that is not socially recognised in universities. Associate deans therefore must manage perceptions of power in order to be effective in an environment that does not acknowledge such power. It is argued that higher education's failure to legitimise organisational power obscures the role and limits leadership capacities. Empowering academic and administrative staff with knowledge regarding power and power practices in academic middle management through continued research is essential to safeguarding collegial processes and ensuring the longevity and vitality of the university.
