Bouar is a market town in the western Central African Republic, lying on the main road from Bangui (437 km) to the frontier with Cameroon (210 km). The city is the capital of Nana-Mambéré prefecture, has a population of 40,353, while the whole sous-préfecture has a population of 96,595 (2003 census). Bouar lies on a plateau almost 1000m above sea level and is known as the site of Camp Leclerc, a French military base.

About seventy groups of megaliths lie in the town and to its north and east. The Bouar Megaliths, dating back to the very late Neolithic Era (c. 3500–2700 BC) were added to the UNESCO World Heritage Tentative List on April 11, 2006 in the Cultural category.

The town's name comes from the Gbaya word for bean, hbouar.

Hundreds of granite megaliths around Bouar were erected during the Late Stone Age by an ancient farming society. These stone megaliths are nowadays known as tanzunu in Gbaya.

The Gbaya people settled in the region around the 1500s. The settlement of Bouar itself was founded circa 1840 by chief Bogbafeï on the site of a bean field. His grandson, Mbarta, served as the chief between 1904 and 1916 and nowadays is remembered as a local hero.

In 1882, France invaded Central Africa and 1894, the borders of French Congo encompassed Bouar. In 1911, the area around Bouar was ceded by France to Germany under the terms of the Morocco-Congo Treaty, becoming part of the German colony of Neukamerun until it was reconquered by the French during World War I. The Germans eventually settled in the town around Christmas of 1913, where they constructed a military post and a road. In 1928, the town became part of the French colony of Ubangi-Shari.

The colonial town centre was occupied and burned down in the late 1920s by Gbaya rebels during the Kongo-Wara rebellion. This was the most significant period in which the Gbaya population and others resisted French colonial rule in Ubangi-Shari.

In 1948, the administrative centre of Ouham-Pendé prefecture was moved from Bozoum to Bouar. Later, the western part of the prefecture would become Nana-Mambéré prefecture with Bouar as its capital, while Bozoum would become the capital of the remaining Ouham-Pendé prefecture. Electricity was installed in Bouar in 1952. In 1960 the colony became independent as the Central African Republic.
