The paper examined the effect of currency devaluation on the Non-oil export of Nigeria. The study covered the period of 1986 to 2018. Secondary data were sourced from Central Bank of Nigeria Statistical Bulletin of various issues. Independent variables include: Inflation Rate (INFR), Exchange Rate (EXR), and Money Supply (MS) while Non-Oil Export (NOE) represented the dependent indicator. Ordinary Least Square Regression Model was used to analyze the short run relationship between variables used for the study. The variables were also subjected to Augmented Dickey Fuller and Philip Perron Unit Root test, Johansen Co-integration and Granger Causality Tests was adopted to analyze the effect of currency devaluation on non-oil export in Nigeria. The result showed that EXR had a negative significant effect while MS had positive significant influence on non-oil export but INFR had negative but insignificant relationship on the dependent variable in Nigeria hence devaluation of currency influenced non-oil export in Nigeria negatively. The Nigerian Government needs to increase its competitive chances by either revaluating its currency or banning importation of some items produced locally to boost the domestic economy. The study provides the extent at which the devaluation of currency influences the non-oil export in Nigeria.
