This work deals with the effect of transformational leadership (TL) on organisational performance (OP) through the mediating roles of organisational learning (OL) and open innovation (OI). Data was collected from 202 respondents in Tunisian enterprises using non-probabilistic convenience sampling. Based on structural equation modelling, the findings demonstrate a positive effect of TL on OP through an OI mediation. The study highlighted the direct and indirect effects of TL on OP through a double partial mediation of OI and OL. The document sheds new light on the gaps between TL and entrepreneurial leadership, not as a continuum, but as coexisting entrepreneurial leadership styles.
