Ouagadougou is the capital of Burkina Faso and the administrative, communications, cultural, and economic centre of the nation. It was the capital of the historic Mossi kingdom of Wagadugu (founded in the 15th century) and the seat of the morho naba (“great king”) of the Mossi people. Islam became the religion of the kings under Naba Dulugu (ruled 1796?–1825?). The morho naba still lives in the city, though his powers were greatly eclipsed by the French colonial and post-independent administrations. It is also the country's largest city, with a population of 2,200,000 in 2015. The city's name is often shortened to Ouaga. The inhabitants are called ouagalais. The spelling of the name Ouagadougou is derived from the French orthography common in former French African colonies.

Ouagadougou's primary industries are food processing and textiles. It is served by an international airport and is linked by rail to Abidjan in the Ivory Coast and, for freight only, to Kaya. There are several highways linking the city to Niamey, Niger, south to Ghana, and southwest to Ivory Coast. Ouagadougou has one of West Africa's largest markets, which burned down in 2003 and has since reopened with better facilities and improved fire-prevention measures. Other attractions include the National Museum of Burkina Faso, the Moro-Naba Palace (site of the Moro-Naba Ceremony), the National Museum of Music, and several craft markets.

Ouagadougou's first municipal elections were held in 1956. The city is governed by a mayor who is elected to a five-year term, two senior councillors, and 90 councillors. The city is divided into five arrondissements, consisting of 30 sectors, which are subdivided into districts. Districts of Ouagadougou include Gounghin, Kamsaoghin, Koulouba, Moemmin, Niogsin, Paspanga, Peuloghin, Bilbalogho, and Tiendpalogo. Seventeen villages comprise the Ouagadougou metropolitan area, which is about 219.3 km2 (84.7 sq mi).

The population of this area is estimated at 1,475,000, 48% of whom are men and 52% women. The rural population is about 5% and the urban population about 95% of the total, and the density is 6,727 inhabitants per square kilometre, according to the 2006 census. Ouagadougou's communes have invested in huge city-management projects. This is largely because Ouagadougou constitutes a 'cultural centre' by merit of holding the SIAO (International Arts and Crafts fair) and the FESPACO (Panafrican Film and Television Festival of Ouagadougou). Moreover, the villages' growing affluence allows for such investment, and the population's rapid growth necessitates it.
 

The economy of Ouagadougou is based on industry and commerce. Some industrial facilities have relocated from Bobo-Dioulasso to Ouagadougou, which has made the city an important industrial centre of Burkina Faso. The industrial areas of Kossodo and Gounghin are home to several processing plants and factories. The industry of Ouagadougou is a sector that fuels urban growth, as people move to the city from the countryside to find employment in industry. The Copromof workshop in Ouagadougou sews cotton lingerie for the French label "Atelier Augusti."Ouagadougou is an important commercial centre. It is a centre where goods are collected and directed to rural areas. With a large consumer base, large amounts of energy sources, raw materials for buildings, agricultural products and livestock products are imported to the city.The economy is dominated by the informal sector, which is characterized by petty commodity production, and workers not necessarily having salaries. Traditional, informal trade is widespread and concentrated around markets and major roads, as well as in outlets in neighborhoods. There are also instances of modern economic practices with workplaces having qualified, stable labor forces, or more traditional forms of business such as family businesses.The tertiary sector is also an important part of the economy. This comprises communications, banking, transport, bars, restaurants, hotels, as well as administrative jobs.

The Bangr-Weoogo urban park (area: 2.63 km2 (1 sq mi)), before colonialism, belonged to the Mosse chiefs. Considering it a sacred forest, many went there for traditional initiations or for refuge. The French colonists, disregarding its local significance and history, established it as a park in the 1930s. In 1985, renovations were done in the park. In January 2001, the park was renamed "Parc Urbain Bangr-Weoogo", meaning "the urban park of the forest of knowledge". Another notable park in Ouagadougou is the "L'Unité Pédagogique", which shelters animals in a semi-free state. This botanic garden/biosphere system stretches over 8 hectares (20 acres) and also serves as a museum for the country's history. "Jardin de l'amitié Ouaga-Loudun" (Garden of Ouaga-Loudun Friendship), with a green space that was renovated in 1996, is a symbol of the twin-city relationship between Ouagadougou and Loudun in France. It is situated in the centre of the city, near the "Nation Unies' crossroads".
