The main objective of this study is to investigate the impact of government pension funding on economic growth in Nigeria. For this purpose, real GDP, government expenditure on pension, corruption perception index and pension reform dummy variables are used in this study. The OLS technique of analysis was adopted with the application of the ADF unit root test method and the residual based co-integration. The unit root test results reveal that all the variables used in this study are found to be integrated at an order one I(1). The variables exhibited no long run equilibrium relationship; thus, the level form (long-run) analysis was used. The long run estimated results reveal that government expenditure on pension and gratuity has significant impact on economic growth. Based on our findings, we conclude that government expenditure on pension has a significant effect on economic growth in Nigeria
