Transport in Niger is crucial to the economy of this vast landlocked nation, with cities separated by huge uninhabited deserts, mountain ranges, and other natural features. A poor nation, Niger's transport system was little developed during the colonial period (1899–1960), relying upon animal transport, human transport, and limited river transport in the far south west and south east. No railways were constructed in the colonial period, and roads outside the capital remained unpaved. The Niger River is unsuitable for river transport of any large scale, as it lacks depth for most of the year, and is broken by rapids at many spots. Camel caravan transport was historically important in the Sahara desert and Sahel regions which cover most of the north.

Transport, including motor vehicles, highways, airports, and port authorities, are overseen by the Nigerien Ministry of Transport's Directorate for Land Water and Air Transport ("Ministère des Transport et de l'aviation civile/Direction des Transports Terrestres, Maritimes et Fluviaux"). Border controls and import/export duties are overseen by an independent tax police, the "Police du Douanes. Air traffic control is overseen and operated in conjunction with the pan-African ASECNA, which bases one of its five air traffic zones at Niamey's Hamani Diori International Airport. A non-governmental body, the Nigerien Council of Users of Public Transport ("Conseil Nigérien des Utilisateurs des Transports Publics CNUT") advocates on behalf of users of public transport, including roads and airports.

Niger (French pronunciation: [niʒɛʁ], but occasionally pronounced as /niːˈʒɛər/ or ⁱ/ˈnaɪdʒər/), officially the Republic of Niger, is a landlocked country in Western Africa, named after the Niger River. It borders Nigeria and Benin to the south, Burkina Faso and Mali to the west, Algeria and Libya to the north and Chad to the east. Niger covers a land area of almost 1,270,000 km², making it the largest nation in West Africa, with over 80 percent of its land area covered by the Sahara desert. The country's predominantly Islamic population of just above 15,000,000 is mostly clustered in the far south and west of the nation. The capital city is Niamey, located in the far southwest corner of Niger.

Niger is a developing country, and consistently ranks as one of the lowest ranks of the United Nations' Human Development Index (HDI), 186th of 187 countries in 2011. Much of the non-desert portions of the country are threatened by periodic drought and desertification. The economy is concentrated around subsistence and some export agriculture clustered in the more fertile south, and the export of raw materials, especially uranium ore. Niger remains handicapped by its landlocked position, desert terrain, poor education and poverty of its people, lack of infrastructure, poor health care, and environmental degradation.
