This paper seeks to investigate the determinants of banking network profitability in Iran from 2007 to 2012. The results of our study indicate that both bank-specific factors and macroeconomic factors influence banks’ profitability in Iran. Results confirm that bank profitability is significantly influenced by investment to total assets ratio, non-performing loans to total assets ratio, and time deposit to total assets ratio. Among external factors, it turns out that economic growth rate has a significant positive impact on bank profitability. JEL Classifications: C23, G21, M20
