Purpose: Despite the growing interest in the study of authentic leadership, there is little empirical evidence of the consequences of this type of leadership for companies. On the other hand, the mediating variables that may explain these results have not been explored in depth either. Although the academic literature suggests, from a theoretical point of view, that these leaders could favour innovation, little has been studied from an empirical perspective. This study aims to try to cover these gaps. Design/methodology/approach: The main goal of this study is to analyse the mediating effect of organisational learning capability in the relationship between authentic leadership and innovation success. Considering a sample frame of 263 Spanish companies, this study tested the proposed hypotheses through structural equations. Findings: The results provide empirical evidence of the positive effect of authentic leaders to promote organisational learning capability. In addition, this study confirms the positive effect of organisational learning capability on innovation success. Finally, organisational learning capability mediates the relationship between authentic leadership and innovation success. Originality/value: To the best of the authors' knowledge, this is the first attempt to empirically study the effects of authentic leadership on organisational learning capability and innovation success.
