This study was carried out to evaluate the constraints associated with port hinterland cargo delivery in Nigeria. To achieve this objective, three research questions and three research hypotheses were formulated to guide this study. The data was collected from secondary sources. The secondary data were collected with the help of Nigeria Port Authority statistical bulletin and other journals and articles. The data collected were analyzed using Ordinary Least Square (OLS) regression analysis to test research hypotheses. The study reveals that there is a significant relationship between port hinterland transport and rail transport, there is a positive relationship between port hinterland transport integration and road transport and there is a significant relationship between port hinterland transport and water transport. The study concluded with some recommendations that government should take legislative and policy measures to develop the port system. Nigeria waterways need to be properly dredged so as to encourage vessels of more TEUs to navigate our waterways and government should ensure that port tariffs are moderate to make Nigerian ports more competitive. This would probably bring to an end the issue of diversion of Nigerian bound cargo to our neighboring ports.
