Ilemi Triangle in the context of Southern Nations, Nationalities, and People's Region

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).

The Southern Nations, Nationalities, and Peoples' Region (often abbreviated as SNNPR; Amharic: የደቡብ ብሔር ብሔረሰቦችና ሕዝቦች ክልል, romanized: Yädäbub Bḥer Bḥeräsäbočna Hzboč Kllə) was a regional state in southwestern Ethiopia. It was formed from the merger of five kililoch, called Regions 7 to 11, following the regional council elections on 21 June 1992. Its government was based in Hawassa.

The SNNPR bordered Kenya to the south (including a small part of Lake Turkana), the Ilemi Triangle (a region claimed by Kenya and South Sudan) to the southwest, Oromia region to the north and east. The capital city of the region was Hawassa. The region included major cities and towns like Wolaita Sodo, Arba Minch, Jinka, Dila, Boditi, Areka, Butajira, Welkite, Bonga, Hosaena and Worabe.

Turkana County is a county in northwestern Kenya in the Northern Rift region. It is home to the Turkana people. It is Kenya'slargest county by land area of 77,597.8 km followed by Marsabit County with an area of 66,923.1 km. It is bordered by the countries of Uganda to the west; South Sudan and Ethiopia, including the disputed Ilemi Triangle, to the north and northeast; and Lake Turkana to the east. To the south and east, neighbouring counties in Kenya are West Pokot, Baringo and Samburu Counties, while Marsabit County is on the opposite (i.e. eastern) shore of Lake Turkana. Turkana's capital and largest town is Lodwar. The county had a population of 926,976 according to the 2019 census report. It is projected to reach 1.048 million people in 2024
