This paper examines the effect of economic and non-economic factors on international tourist arrival in Nigeria. Annual data on tourist arrival from 53 countries and explanatory variables from 2010-2016 were analyzed using the dynamic panel data regression technique. Results suggest that travel cost, internet use, political stability and number of hotel rooms are the main determinants of tourist flows. The income of tourist-origin countries outside Africa negatively and significantly affects tourist arrival. Travel cost has a robust negative effect on tourists from within and outside Africa. The number of hotel rooms and urbanization rate positively influence tourist arrival, indicating the importance of tourism infrastructure. Government and policymakers must provide an enabling business environment, infrastructure, and policies to improve the country's global competitiveness.
