The main objective of the study was to determine whether the fact that the chairpersons of the boards of cooperative banks in Poland are women, it affects the financial performance of these banks. The study used data for the years 2010-2014 from 40 cooperative banks in Poland. In the course of the study, it was found that the banks managed by women are significantly smaller than men’s managed banks, and hence the financial result is generally lower. However, the financial performance ratios in these banks were generally higher. Smaller banks are generally in rural areas, and banks with a larger total balance sheet are usually located in urban areas.
