Niger is a landlocked nation in West Africa located along the border between the Sahara and Sub-Saharan regions. It lies between latitudes 11° and 24°N, and longitudes 0° and 16°E. Niger's area is 1,267,000 square kilometres (489,191 sq mi) of which 300 square kilometres (116 sq mi) is water. This makes it slightly less than twice the size of the US state of Texas, and the world's twenty-second largest country.

Niger borders seven countries and has a total perimeter of 5,697 kilometres (3,540 mi). The longest border is with Nigeria to the south (1,497 km or 930 mi). This is followed by Chad to the east, at 1,175 km (730 mi), Algeria to the north-northwest (956 km or 594 mi), and Mali at 821 km (510 mi). Niger also has small borders in its far southwest with Burkina Faso at 628 km (390 mi) and Benin at 266 km (165 mi) and to the north-northeast Libya at 354 km (220 mi).

The lowest point is the Niger River, with an elevation of 200 metres (656 ft). The highest point is Mont Idoukal-n-Taghès in the Aïr Mountains at 2,022 m (6,634 ft).

The North of the country is covered by large deserts and semi deserts. The typical mammal fauna consists of Addax antelopes, Scimitar-horned oryx, gazelles and in mountains Barbary sheep. One of the largest reserves of the world, the Aïr and Ténéré National Nature Reserve was founded in the northern parts of the Niger to protect these rare species.

The southern parts of Niger are naturally dominated Savannahs. The W National Park, situated in the bordering area to Burkina Faso and Benin, belongs to one of the most important areas for wildlife in Western Africa, which is called the WAP (W-Arli-Pendjari) Complex. It has the most important population of the rare West African lion and one of the last populations of the Northwest African cheetah. Other wildlife includes elephants, buffaloes, roan antelopes, kob antelopes and warthogs. The West African giraffe is currently not found in the W National Park, but further north in Niger, where it has its last relict population.
