In this work, we are trying to examine the efficiency of Islamic banks in North Africa. This study concerns eight Islamic banks belong to five countries. The data are collected from the official websites of these banks for a period of time extends between 2010 and 2014 (five years). We appeal to the method of analysis by financial ratios and the DEA, specially the Window Analysis. In the light of the analyse by the financial ratios, we note that the performance of Islamic banks in North Africa is in decline. According to the non-parametric method DEA, the only efficient bank C is the Algerian bank al-Salam. But, the Islamic Bank of Mauritania was in last row between the Islamic banks in North Africa with increasing returns to scale.
