The study examined the impact of foreign private investment on Nigeria economic growth between 1980 and 2010. The empirical analysis was based on multiple regression technique. Economic growth was proxied by Gross Domestic Product and the result showed that foreign private investment, gross fixed capital formation and net export are positively related with economic growth while inflation rate has a negative relationship with economic growth. Hence increased inflow of foreign private investment into the country enhances economic growth in Nigeria. It is recommended that government should therefore strive to provide a conducive environment for foreign private investment in Nigeria through appropriate fiscal, monetary and general economic policies and stable macroeconomic environment.
