The aim of our research is to investigate the relationship between risk management, corporate governance and performance in Tunisian financial institutions. Mainly, this research seeks to examine the effect of risk management and some board's features on financial performance. Empirical analyses are conducted from a sample of 20 Tunisian financial institutions over the period 2002-2011 using an OLS regression. The study shows that board size affect performance significantly. Most importantly, the existence of a risk committee within the institution has a negative and significant effect on performance.
