The economic growth of a country depends on how the units of the economy are financially included to be economically active and viable. This paper examines the role commercial banks play in financial inclusion on economic growth by using panel data on 10 West African countries from 2004 to 2015. Four econometric models are used to statistically infer on the outcome of the study and to find out the long run relationship between financial inclusion and economic growth. The empirical results infer that there is a long run impact of financial inclusion on economic growth and also have a strong positive relationship or impact on economic growth with an effective role played by the commercial banks. The study recommends that commercial banks should be innovative and also reach out to the unbanked populace with enticing products and services. Moreover, governments should create an enabling environment for high financial literacy in education and awareness creation.
