The following is a list of the 100 largest cities in Africa by urban population using the most recent official estimate. This reflects only cities located geographically in Africa including related islands.

The 21st Century Maritime Silk Road (Chinese: 21世纪海上丝绸之路), commonly just Maritime Silk Road (MSR), is the sea route part of the Belt and Road Initiative which is a Chinese strategic initiative to increase investment and foster collaboration across the historic Silk Road.

The maritime silk road essentially runs through the Indo-Pacific and then the Indo-Mediterranean from the Chinese coast to the south via Hai Phong to Jakarta, Singapore and Kuala Lumpur through the Strait of Malacca then via Colombo in Sri Lanka towards the southern tip of India via Malé, to the East African Mombasa, from there to Djibouti, then through the Red Sea via the Suez Canal to the Mediterranean, then via Haifa, Istanbul and Athens to the Upper Adriatic region to the northern Italian hub of Trieste with its international free port and its rail connections to Central Europe and the North Sea.

Kenya, officially the Republic of Kenya, is a country located in East Africa. With an estimated population of more than 53.3 million as of mid-2025, Kenya is the 27th-most-populous country in the world and the 7th most populous in Africa. Kenya's capital and largest city is Nairobi. The second-largest and oldest city is Mombasa, a major port city located on Mombasa Island. Other major cities within the country include Kisumu, Nakuru and Eldoret. Going clockwise Kenya is bordered by South Sudan to the northwest (though much of that border includes the disputed Ilemi Triangle), Ethiopia to the north, Somalia to the east, the Indian Ocean to the southeast, Tanzania to the southwest, and Lake Victoria and Uganda to the west.

Kenya's geography, climate and population vary widely. In western rift valley counties, the landscape includes cold, snow-capped mountaintops (such as Batian, Nelion, and Point Lenana on Mount Kenya) with vast surrounding forests, wildlife, and fertile agricultural regions in temperate climates. In other areas, there are dry, arid, and semi-arid climates, as well as absolute deserts (such as Chalbi Desert and Nyiri Desert).

Kilindini Harbour is a large, natural deep-water inlet extending inland from Mombasa, Kenya. It is 25–30 fathoms (46–55 m) at its deepest center, although the controlling depth is the outer channel in the port approaches with a dredged depth of 17.5 m (57 ft). It serves as the harbour for Mombasa, with a hinterland extending to Uganda. Kilindini Harbour is the main part of the Port of Mombasa, the only international seaport in Kenya and the biggest port in east Africa. It is managed by the Kenya Ports Authority (KPA). Apart from cargo handling, Mombasa is frequented by cruise ships.

Kilindini is a Swahili term meaning "deep down" or "in the depths" in reference to the depth of the channel. Kilindini Harbor is an example of a natural geographic phenomenon called a ria, formed millions of years ago when the sea level rose and engulfed a river that was flowing from the mainland.

The Swahili coast (Swahili: Pwani ya Waswahili) is a coastal area of East Africa, bordered by the Indian Ocean and inhabited by the Swahili people. It includes Sofala (located in Mozambique); Mombasa, Gede, Pate Island, Lamu, and Malindi (in Kenya); and Dar es Salaam and Kilwa (in Tanzania). In addition, several coastal islands are included in the Swahili coast, such as Zanzibar and Comoros.

Areas of what is today considered the Swahili coast were historically known as Azania or Zingion in the Greco-Roman era, and as Zanj or Zinj in Middle Eastern, Indian and Chinese literature from the 7th to the 14th century. The word "Swahili" means people of the coasts in Arabic and is derived from the word sawahil ("coasts").

Mombasa Island is a 5 by 3 km (3.1 by 1.9 mi) coral outcrop located on Kenya's coast on the Indian Ocean, which is connected to the mainland by a causeway. Part of the city of Mombasa is located on the island, including the Old Town.

Eldoret is a city in the Rift Valley region of Kenya. It serves as the capital of Uasin Gishu County. Located in western Kenya and lying south of the Cherangani Hills, the local elevation varies from about 2,100 metres (6,900 ft) at the Eldoret International Airport to more than 2,700 metres (8,900 ft) in nearby areas.

As per the 2019 population census, Eldoret has a population of 475,716 people and is the fifth most populated urban area in the country after Nairobi, Mombasa, Nakuru and Ruiru.

Kenya Ports Authority (KPA) is a state corporation with the responsibility to "maintain, operate, improve and regulate all scheduled seaports" on the Indian Ocean coastline of Kenya, including principally Kilindini Harbour at Mombasa. Other KPA ports include Lamu, Malindi, Kilifi, Mtwapa, Kiunga, Shimoni, Funzi and Vanga.

Mombasa County is one of the 47 counties of Kenya. Its capital city is Mombasa. In terms of economy, it is second most developed after Nairobi City County. Mombasa was one of the districts of Kenya until 2013 when it was reconstituted as a county on the same boundaries. It is the smallest county in Kenya, covering an area of 229.7 km, excluding 65 km of water mass. The county is situated in the southeastern part of the former Coast Province, bordering Kilifi County to the north, Kwale County to the south west and the Indian Ocean to the east. Administratively, the county is divided into seven divisions, eighteen locations and thirty sub-locations.

Prior to 2013, Kenya was divided into eight provinces, which were subdivided into 47 counties. The former Coast Province contained six counties, of which Mombasa was one. It is situated in the southeast of Coast Province, and is the smallest county in size, covering an area of 212.5 km. The county lies between latitudes 3°56′ and 4°10′ south of the equator and longitudes 39°34′ and 39°46′ east.
