Financial crisis which were occured more frequent intervals and have been encountered especially after 1990, damaged particularly Turkish Banking System then all financial system and caused to be determine by researchers seriously. In this line, the aim of this study is searching the effect of the commercial banks? profitability performance in Turkish Banking System comparing with the financial crisis which were occured in 1999, 2000, 2001 and 2008.

In the implementation phase, firstly independent variables were included the analyze of Pearson and Factor and they were decreased, then those variables with dependent variables were taken into analyze of binary logistic regression and the comparison of financial crisis was made. The results of analyze were evaluated in the general frame.As a result of this study, the ratio group of income and expense took over for dependent variables which are the profitability of asset and the profitability of equity at these years which were analyzed.
