This study examines the impact of Capital Market performance on economic growth of Nigeria for the period 1983 - 2010. Economic growth was proxied by gross domestic product while capital market performance was measured by market capitalization, total new issues, volume of transaction and listed equities. Data was collected using secondary source of data only. The technique employed was multiple regression as tool of analysis for the study. The findings of the study shows that the capital market performance has positively and significantly impacted on the Nigerian economy within the period of the study (1983- 2010). The study therefore, recommends among others that the Central Bank of Nigeria (CBN), the Nigerian Stock Exchange (NSE) and Security and Exchange Commission (SEC) should ensure free flow of information in the market. This is necessary in order to attract more investors and increase new issues which will automatically increase the quantum of market capitalization that will result in improving the performance of the Nigerian capital market.
