{{Short description|Defunct administrative district in the former Rift Valley Province of Kenya}} '''Keiyo District''' (also known as ''Elgeyo district'' or Elgeiyo) is a defunct administrative district in the former Rift Valley Province of Kenya. The district was formed in 1994, when the Elgeyo-Marakwet District was split into two — the other half was Marakwet District. According to the 2009 Kenya Population and Housing Census, Keiyo District had a population of 182,875 [https://web.archive.org/web/20090530045717/http://www.cck.go.ke/html/final_annex1_cover_status.pdf]. Its capital was located in the Iten/Tambach town. In 2010, the districts were re-joined as Elgeyo-Marakwet County.
Local people are mostly of the Keiyo tribe. Many famous Kenyan runners come from the district, including Saif Saaeed Shaheen (born Stephen Cherono), Vivian Cheruiyot and Lornah Kiplagat. The world record marathon holder, Kelvin Kiptum, was also from the region. The area is used by local and foreign athletes for high-altitude training.
Mining of fluorite by the Kenya Fluorspar Company is the largest industry in the former district.<ref name="eastafrican2">The East African, September 15, 2008: [https://www.theeastafrican.co.ke/news/-/2558/471072/-/item/1/-/29l07g/-/index.html Flourspar enters European market despite Chinese competition (page 2)] {{Webarchive|url=https://web.archive.org/web/20110720074948/https://www.theeastafrican.co.ke/news/-/2558/471072/-/item/1/-/29l07g/-/index.html |date=2011-07-20 }}</ref><ref>Kerio Valley Development Authority: [http://www.regional-dev.go.ke/kvda/minerals.htm Mineral Resources Exploration ]{{Dead link|date=February 2020 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>
