The Chad National Museum (Musée National N'Djamena) is the national museum of Chad. It is located in the capital city of N'Djamena at near Avenue Felix Eboue, with a mailing address of BP 638, Fort Archambault. The museum was established on October 6, 1962 in temporary quarters under the name of Chad National Museum, Fort-Lamy, reflecting the earlier, colonial name of Chad's capital. In 1964, it moved to the former town hall, near the Place de l'Independence.

At the time of its establishment, it had four rooms:

The prehistory room, at least in 1965, included items related to pebble culture, including material from the Amgamma cliff, Stone Age implements, axes with helve-holes, nether millstones, and quartz and obsidian arrowheads. The museum at one time included a full-sized ochre reproduction of a hunting scene from the first millennium B.C. The collection also included baked bricks, some attributed to Boulala and Babalia people, items discovered at the Bouta-Kabira sanctuary including human masks, bronze objects and bone tools.

Chad ⁱ/ˈtʃæd/ (French: Tchad, Arabic: تشاد‎ Tšād), officially known as the Republic of Chad, is a landlocked country in Central Africa. It is bordered by Libya to the north, Sudan to the east, the Central African Republic to the south, Cameroon and Nigeria to the southwest, and Niger to the west. Due to its distance from the sea and its largely desert climate, the country is sometimes referred to as the "Dead Heart of Africa".

Chad is divided into multiple regions: a desert zone in the north, an arid Sahelian belt in the centre and a more fertile Sudanese savanna zone in the south. Lake Chad, after which the country is named, is the largest wetland in Chad and the second largest in Africa. Chad's highest peak is the Emi Koussi in the Sahara, and N'Djamena, (formerly Fort-Lamy), the capital, is the largest city. Chad is home to over 200 different ethnic and linguistic groups. Arabic and French are the official languages. Islam and Christianity are the most widely practiced religions.

Beginning in the 7th millennium BC, human populations moved into the Chadian basin in great numbers. By the end of the 1st millennium BC, a series of states and empires rose and fell in Chad's Sahelian strip, each focused on controlling the trans-Saharan trade routes that passed through the region. France conquered the territory by 1920 and incorporated it as part of French Equatorial Africa.

A national museum is a museum maintained by a nation.
