Ouagadougou or Wagadugu is the capital of Burkina Faso, and the administrative, communications, cultural and economic centre of the nation. It is also the country's largest city, with a population of 2,415,266 in 2019. 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.

On 15 January 2016, gunmen armed with heavy weapons attacked the Cappuccino restaurant and the Splendid Hotel in the heart of Ouagadougou, the capital of Burkina Faso. The number of fatalities reached 30, while at least 56 were wounded; a total of 176 hostages were released after a government counter-attack into the next morning as the siege ended. Three perpetrators were also killed. The nearby YIBI hotel was then under siege, where another attacker was killed. Notably, former Swiss MPs Jean-Noël Rey and Georgie Lamon were killed. Responsibility for the attack was claimed by Al-Qaeda in the Islamic Maghreb (AQIM) and Al-Mourabitoun.
