The aim of this study is to test the theoretical model which hypothesizes that academics' academic intellectual leadership affects their perceptions of perceived organizational support and organizational citizenship. In line with this general purpose, it was determined whether the perceptions of academics' intellectual leadership affect their perceptions of perceived organizational support and organizational citizenship. The causal design was used in the study. The sample population of the study is composed of 731 academics working in 13 universities selected by convenience sampling from the Central Anatolia, Aegean, Black Sea and East Anatolia regions of Turkey. The data were collected with Academic Intellectual Leadership Scale, Perceived Organizational Support Scale, and Organizational Citizenship Scale in the 2018-2019 academic year. Mean, standard deviance, and correlation analysis were used for the analysis of the descriptive data, and path analysis was used to test the theoretical model. The findings show that academics' academic intellectual leadership perceptions positively effect their perceptions of perceived organizational support (gamma=.24) and organizational citizenship (gamma=.38). The results were discussed in light of the relevant literature and suggestions were made to the practitioners, policy makers, and researchers.
