Accra (; Ga: Ga or Gaga; Twi: Nkran; Ewe: Gɛ; Dagbani: Ankara) is the capital and largest city of Ghana, located on the southern coast at the Gulf of Guinea, which is part of the Atlantic Ocean. As of 2021 census, the Accra Metropolitan District, 20.4 km2 (7.9 sq mi), had a population of 284,124 inhabitants, and the larger Greater Accra Region, 3,245 km2 (1,253 sq mi), had a population of 5,455,692 inhabitants. In common usage, the name "Accra" often refers to the territory of the Accra Metropolitan District as it existed before 2008, when it covered 199.4 km2 (77.0 sq mi). This territory has since been split into 13 local government districts: 12 independent municipal districts (total area: 179.0 km2) and the reduced Accra Metropolitan District (20.4 km2), which is the only district within the capital to be granted city status. This territory of 199.4 km2 contained 1,782,150 inhabitants at the 2021 census, and serves as the capital of Ghana, while the district under the jurisdiction of the Accra Metropolitan Assembly proper (20.4 km2) is distinguished from the rest of the capital as the "City of Accra".

Formed from the merger of distinct settlements around British Fort James, Dutch Fort Crêvecoeur (Ussher Fort), and Danish Fort Christiansborg as Jamestown, Usshertown, and Christiansborg respectively, Accra served as the capital of the British Gold Coast between 1877 and 1957 and has since transitioned into a modern metropolis. The capital's architecture reflects this history, ranging from 19th-century colonial architecture to modern skyscrapers and apartment blocks.

Accra is the Greater Accra Region's economic and administrative hub, and serves as the anchor of the larger Greater Accra Metropolitan Area (GAMA), which is inhabited by about 4 million people, making it the thirteenth-largest metropolitan area in Africa. In 2020, the Globalization and World Cities Research Network think tank designated Accra as a "Gamma −" level global city, indicating a growing level of international influence and connectedness.
