Kenya does not have states — it is divided into 47 counties, which serve as the country's primary administrative and political units under the 2010 Constitution. These counties replaced the older system of 8 provinces and 1 capital district, decentralising power away from Nairobi and giving each region its own elected government. So if you are asking how many "states" Kenya has, the precise answer is 47 county governments.
Counties, Not States: A Quick Clarification
Unlike federal countries such as the United States, India, or Nigeria, Kenya is a unitary republic, so it has no states in the formal sense. The equivalent sub-national tier is the county. The shift happened in 2010 when Kenyans approved a new constitution by referendum, and the counties became operational after the 2013 general election. Before that, Kenya was organised into eight provinces — Central, Coast, Eastern, Nairobi, North Eastern, Nyanza, Rift Valley, and Western — administered largely from the centre. The 47 counties were carved out of these former provinces, with the giant Rift Valley Province alone splitting into 14 separate counties.
The Full List of Kenya's 47 Counties
Each of the 47 counties has its own governor, deputy governor, and county assembly. They are: Baringo, Bomet, Bungoma, Busia, Elgeyo-Marakwet, Embu, Garissa, Homa Bay, Isiolo, Kajiado, Kakamega, Kericho, Kiambu, Kilifi, Kirinyaga, Kisii, Kisumu, Kitui, Kwale, Laikipia, Lamu, Machakos, Makueni, Mandera, Marsabit, Meru, Migori, Mombasa, Murang'a, Nairobi, Nakuru, Nandi, Narok, Nyamira, Nyandarua, Nyeri, Samburu, Siaya, Taita-Taveta, Tana River, Tharaka-Nithi, Trans-Nzoia, Turkana, Uasin Gishu, Vihiga, Wajir, and West Pokot. Their names draw on geographic landmarks, rivers, lakes, and the ethnic communities who live there.
How the County System Works
Devolution is the heart of Kenya's modern governance. Each county receives a guaranteed share of national revenue — constitutionally set at no less than 15% of the most recently audited national accounts — and uses it to deliver services close to citizens. County responsibilities include:
- Health: running county and sub-county hospitals, clinics, and primary care.
- Agriculture: crop and livestock support, extension services, and fisheries.
- Local infrastructure: county roads, street lighting, water, and sanitation.
- Planning: land use, county development, trade licensing, and markets.
At the national level, the Senate represents the counties, with each county electing one senator to safeguard county interests and oversee how devolved funds are used. This structure was a direct response to the disputed 2007 election and the violence that followed, when many Kenyans felt power and resources were concentrated in too few hands.
Biggest, Smallest, and Most Populous
Kenya's counties vary enormously in size and population. Nairobi County, which is both the capital and the economic engine of the nation, is the most populous with well over 4 million residents packed into a relatively small footprint. By contrast, Lamu County on the Indian Ocean coast is among the least populated, home to roughly 140,000 people. In terms of land area, the northern county of Turkana is the largest at about 68,680 km², a vast and arid region bordering Uganda, South Sudan, and Ethiopia. Mombasa, the historic port city, is one of the smallest counties by area yet densely settled and economically vital. This contrast between sprawling northern counties and compact, crowded urban ones shapes how revenue and services are distributed across the country.
Notable Counties Worth Knowing
Several counties stand out for their landmarks and significance. Lamu County contains Lamu Old Town, a UNESCO World Heritage Site and one of the oldest continuously inhabited Swahili settlements in East Africa. Marsabit County in the far north holds part of Lake Turkana, the world's largest permanent desert lake. Narok County is home to the Maasai Mara National Reserve, famous for the annual wildebeest migration, while Nakuru County hosts the flamingo-filled Lake Nakuru. For travellers and learners alike, the counties offer a tidy way to understand Kenya's diverse geography, from coral coastline to highland tea estates to desert frontier.

Frequently Asked Questions
Does Kenya have states or provinces?
Neither in the current system. Kenya abolished its 8-province structure under the 2010 Constitution and replaced it with 47 counties, each with its own elected county government. The provinces are now largely historical reference points.
When were Kenya's 47 counties created?
The counties were established by the 2010 Constitution and became fully operational after the March 2013 general election, when Kenyans first voted for governors and county assemblies. This launched one of Africa's most ambitious devolution programmes.
What is the largest county in Kenya?
Turkana County is the largest by land area at roughly 68,680 km². It sits in Kenya's arid northwest and borders three other countries. Nairobi County, though tiny by area, is the largest by population.
How are Kenya's counties governed?
Each county is led by an elected governor and a county assembly of ward representatives. Counties receive at least 15% of national revenue and manage local health, agriculture, roads, and planning, while one senator per county represents them in the national Senate.
