Tunisia is a country located in Northern Africa, bordering the Mediterranean Sea, between Algeria and Libya. Its geographic coordinates are . Tunisia occupies an area of 163,610 square kilometres, of which 8,250 are water. Tunisia borders Algeria for 965 km and Libya for 459 km.
- Contiguous zone: 24 nmi (44.4 km; 27.6 mi)
- Territorial sea: 12 nmi (22.2 km; 13.8 mi)
Tunisia is situated on the Mediterranean coast of North Africa, midway between the Atlantic Ocean and the Nile Delta. It is bordered by Algeria on the west and Libya on the south east. It lies between latitudes 30° and 38°N, and longitudes 7° and 12°E. An abrupt southward turn of the Mediterranean coast in northern Tunisia gives the country two distinctive Mediterranean coasts, west-east in the north, and north-south in the east
Tunisia is about the size of the American state of Wisconsin. Despite its relatively small size, Tunisia has great environmental diversity due to its north-south extent. Its east-west extent is limited. Differences in Tunisia, like the rest of the Maghreb, are largely north-south environmental differences defined by sharply decreasing rainfall southward from any point. The Dorsal, the eastern extension of the Atlas Mountains, runs across Tunisia in a northeasterly direction from the Algerian border in the west to the Cape Bon peninsula in the east. North of the Dorsal is the Tell, a region characterized by low, rolling hills and plains, again an extension of mountains to the west in Algeria. In the Khroumerie, the northwestern corner of the Tunisian Tell, elevations reach 1,050 meters (3,440 feet) and snow occurs in winter. The Sahel, a broadening coastal plain along Tunisia's eastern Mediterranean coast, is among the world's premier areas of olive cultivation. Inland from the Sahel, between the Dorsal and a range of hills south of Gafsa, are the Steppes. Much of the southern region is semi-arid and desert. Tunisia has a coastline 1,148 kilometres (713 miles) long. In maritime terms, the country claims a contiguous zone of 24 nautical miles (44 kilometres; 28 miles), and a territorial sea of 12 nautical miles (22 kilometres; 14 miles).
Tunisia's climate is hot-summer Mediterranean in the north, where winters are mild with moderate rainfall and summers are hot and dry. Temperatures in July and August can exceed 40°C. Winters are mild with temperatures rarely exceeding above 20°C (exception is the south-west of the country). The south of the country is desert. The terrain in the north is mountainous, which, moving south, gives way to a hot, dry central plain. The south is semiarid, and merges into the Sahara. A series of salt lakes, known as chottzz or shatts, lie in an east-west line at the northern edge of the Sahara, extending from the Gulf of Gabes into Algeria. The lowest point is Chott el Djerid, at −17 m (−55.8 ft), and the highest is Jebel ech Chambi, at 1,544 metres (5,066 ft).

Current environmental issues for Tunisia include:
- Toxic and hazardous waste - disposal is ineffective and presents human health risks
- Water pollution from raw sewage
- Limited natural fresh water resources
- Soil erosion
Tunisia is a party to the following international agreements: Biodiversity, Climate Change, Climate Change-Kyoto Protocol, Desertification, Endangered Species, Environmental Modification, Hazardous Wastes, Law of the Sea, Marine Dumping, Ozone Layer Protection, Ship Pollution (MARPOL 73/78) and Wetlands. Tunisia has signed, but not ratified the Marine Life Conservation agreement.
Tunisia, like other North African countries, has lost much of its prehistoric biodiversity due to the ongoing expanding human population; for example, until historic times there was a population of the endangered primate Barbary Macaque, Macaca sylvanus. The Monk Seal is now extirpated from Tunisia.
This is a list of the extreme points of Tunisia, the points that are farther north, south, east or west than any other location.
- Northernmost point - Iles des Chiens, Bizerte Governorate
- Northernmost point (mainland) – Ras ben Sakka (Ra's al Abyad), Bizerte Governorate*
- Easternmost point – Bel Ahemer on the border with Libya, Medenine Governorate
- Southernmost point – the tripoint with Algeria and Libya, Tataouine Governorate
- Westernmost point - Village of Hizwa located on the border with Algeria due west of Nefta, Tozeur Governorate
- *Note: this is also the northern-most point of the African continent
