TLDR
Niger shares borders with seven countries: Algeria, Libya, Chad, Nigeria, Benin, Burkina Faso, and Mali. That ties it with Sudan and a handful of other African states for the most land neighbors on the continent. Nigeria has the longest shared border (1,497 km); Benin has the shortest (266 km). Several of these borders — especially Niger–Nigeria and Niger–Benin — have opened, closed, and reopened repeatedly since the 2023 coup, so “who does Niger border” and “can you currently cross into Niger” are two different questions with two different answers.

The Seven Neighbors
Niger sits in the middle of the Sahel, the semi-arid belt that runs across Africa just south of the Sahara. Its shape — wide, roughly rectangular, tilted north — puts it in contact with more countries than almost anywhere else on the continent. Going clockwise from the north: Algeria and Libya sit along Niger’s northern edge, where the border runs through open desert with no real natural landmarks to speak of. Chad takes the northeastern flank. Nigeria runs along the entire south. Benin and Burkina Faso sit to the southwest, and Mali closes the loop to the west.
That’s seven countries, which puts Niger in a small club of African nations — alongside Sudan, the Democratic Republic of Congo, and Tanzania — that border more neighbors than almost anyone else on the continent. It’s a direct consequence of colonial-era boundary drawing: France carved most of these borders through the Sahara and Sahel with rulers and longitude lines, which is why several stretches run dead straight for hundreds of kilometers.
Niger Quick Facts
- Capital: Niamey
- Area: roughly 1,267,000 km² (about twice the size of France)
- Population: approximately 26–27 million
- Landlocked: yes — the nearest coastline is over 600 km away, through Benin
- Neighbors: 7 (Algeria, Libya, Chad, Nigeria, Benin, Burkina Faso, Mali)
Border Lengths, Ranked
Not all of Niger’s borders are created equal. Some run for over a thousand kilometers through populated farmland; others cut through empty desert where the nearest checkpoint might be a day’s drive away.
| Neighbor | Border Length | Region |
|---|---|---|
| Nigeria | 1,497 km | South |
| Chad | 1,175 km | East |
| Algeria | 956 km | North |
| Mali | 821 km | West |
| Burkina Faso | 628 km | Southwest |
| Libya | 354 km | Northeast |
| Benin | 266 km | Southwest |
That’s a combined perimeter of roughly 5,700 km — for comparison, that’s longer than the entire driving distance across the continental United States.
Nigeria
Niger’s longest and most consequential border. The two countries share not just a boundary but a name, a river (the Niger River crosses both), and deep ethnic and linguistic ties — Hausa communities live on both sides of the line, often with closer ties to relatives across the border than to their own capitals. This is also Niger’s main economic lifeline: fuel, food, and manufactured goods move north from Nigeria’s markets, and it’s the border that gets the most political attention, because whatever happens to it affects the price of everything in southern Niger within days.
Chad
The Niger–Chad border runs through the Lake Chad Basin in the east and desert further north. It’s thinner on formal crossings than the Nigeria border, and both countries have dealt with cross-border security concerns tied to instability around Lake Chad. Trade here is smaller in volume but locally important — livestock and grain move both directions depending on the season’s rains.
Algeria
The northern border with Algeria runs almost entirely through the Sahara — no rivers, no real towns, just sand and the occasional oasis town like Assamaka on the Niger side, which has become a known transit point for migrants moving north toward Algeria and, eventually, the Mediterranean. Algeria is by far the larger and wealthier of the two countries, and this border matters more for migration routes and smuggling corridors than for conventional trade.
Mali
Niger and Mali share a long western border and a lot in common right now: both are landlocked, both went through military coups in the 2020s, and both are founding members of the Alliance of Sahel States, the security and political pact formed after their governments broke with the West African regional bloc ECOWAS. The border area, particularly near the tri-border zone with Burkina Faso, has also been a hotspot for armed group activity, which has made civilian movement across it harder than the map alone would suggest.
Burkina Faso
The Niger–Burkina Faso border sits at the edge of the so-called “tri-border area” (with Mali), a region that’s seen some of the heaviest insurgent activity in the Sahel over the past several years. Like Mali, Burkina Faso is now aligned with Niger through the Alliance of Sahel States rather than ECOWAS, which has changed the diplomatic — if not always the practical — reality of crossing between the two.
Libya
Niger’s shortest northern border, but not a minor one. Since Libya’s collapse into fragmented governance after 2011, this stretch of desert has functioned as a major corridor for migrants, arms, and fuel smuggling, largely because there’s no functional central authority on the Libyan side to coordinate border control with.
Benin
Short in length, outsized in importance. Because Niger is landlocked, Benin’s Port of Cotonou is Niger’s main gateway to the sea — most of Niger’s imports and a significant share of its oil exports move through Benin. That’s exactly why this border became a flashpoint: when Niger closed it amid a dispute with Benin, it wasn’t a symbolic gesture, it cut off Niger’s most direct route to global shipping.
Why Niger’s Borders Have Been in the News
Static geography facts are one thing; the political reality on the ground has moved fast since Niger’s 2023 military coup, when the presidential guard removed President Mohamed Bazoum. The regional bloc ECOWAS responded with sanctions and pushed member states — including Nigeria and Benin — to close their land borders with Niger, and even threatened military intervention. For months, that meant two of Niger’s most economically important borders were effectively shut.
Since then, the picture has kept shifting. Nigeria reopened its border in 2024 as diplomatic pressure eased. Niger, alongside Mali and Burkina Faso, responded to the whole episode by forming the Alliance of Sahel States, a security and economic pact between the three juntas, and all three announced their intent to leave ECOWAS entirely — a process that formally concluded in early 2025. The Niger–Benin border, tied to that critical oil pipeline and port access, has swung between open and closed multiple times amid separate disputes over troop deployments near the frontier.
None of that changes who Niger’s neighbors are. It changes whether you can currently drive across the line, and that’s worth checking against your government’s current travel advisory before you plan anything that involves land crossings in the region — official country profiles like the CIA World Factbook’s Niger page and country overviews from the World Bank are a reasonable starting point for the stable facts, but border status itself needs a current-as-of-today check, not a Google result from last year.
