In this paper, our purpose is to examine the relationship between the role of Internal Audit (IA), Corporate Governance (CG) and the Audit Committee (AC) in the recent financial crisis in Greece and to investigate the contribution of IA to CG structures as well as its possible, the IA’s role during the financial crisis in Greece. Moreover, little research has been conducted based on the relationship between corporate governance and internal audit during the financial crisis in case of Greece. For this reason, we conducted a survey, using questionnaires, which were sent to the listed companies of the Athens Stock Market. Out of a total of 192 listed companies on the Athens Stock Exchange, the relevant questionnaires were sent to 100 companies. Those companies were selected firstly based on their total turnover and secondly due to the availability of information from company websites such as employees’ numbers and Internal Audit Department Structures. Our conclusion was that Internal Audit adds value to the organization and it can also help the senior management towards the accomplishment of the organizational goals.
