With regards to the ongoing development in investment activities in the Economic Community of West African States(ECOWAS) and the entire African continent is because of institutional reforms and initiation of sound investment policies. Foreign direct investment(FDI) inflow and outflow severs as a source of capital formation for most developing and least developed countries. This paper provides an overview and analyses of the flow of FDI to the ECOWAS region by considering 16 nations under this region in determining their performance towards FDI attraction and their contribution to outward FDI across the globe by the use of the quantitative method. The outcome shows that there is a continuous decline in FDI inflow to the ECOWAS region over the past 10 years. The result also proves that Ghana and Nigeria are the major recipients of foreign direct investment inflows in the West African region. The result further indicates that Nigeria is the major contributor of outward FDI from the ECOWAS region. It is recommended that the region should increase its outward FDI.
