Sub-counties are the decentralised units through which county governments of Kenya will provide functions and services. List of Counties and Sub-Counties in Kenya. Except for the parts which fall under urban areas, sub-counties will coincide with the constituencies created under article 89 of the Constitution of Kenya. Sub-counties will be headed by a sub-county administrator, appointed by a County Public Service Board.

Under the former Constitution of Kenya, the Provinces of Kenya were subdivided into a number of districts (wilaya). In line with restructuring the national administration to fit with the devolved government system brought in by the 2010 Constitution, that came into full effect following elections in March 2013, the 8 provinces and their administrators and districts were replaced by County Commissioners at the county level, while former districts existing as of 2013 were re-organised as sub-counties, and had Deputy Commissioners appointed over them.

Following the Kenyan general election, 2013, these districts and Nairobi now constitute the 47 counties which will be the basis for rolling out devolution as set out in the 2010 Constitution of Kenya (district headquarters are in parenthesis):

More recent (defunct) districts (after 2007 up to March 2013)

Many more districts have been created since then, such that in July 2009 there were 254 districts (an up to 256 districts plus Nairobi on 20 September 2009, when the High Court outlawed 210 of them).

The creation of new districts has been criticised by opponents for being waste of money and a populist attempt to please local residents. The government, however, say new districts bring services closer to the people and will provide security.

The following list contains 208 districts, taken from a Kenyan government website in July 2009 (the list is incomplete, but their number stopped growing after the High Court decision in September 2009):
