Mount Elgon Constituency is an electoral constituency in Bungoma County, Western Kenya. It was formerly the only constituency in the now defunct Mount Elgon District. The constituency was established for the 1963 elections. It has a population of 218,873 people (2019 census). It is currently administered in three administrative units of Mt. Elgon Subcounty headquartered at Kapsokwony town, Cheptais Subcounty headquartered at Cheptais Township, and Kopsiro Subcounty whose headquarter is at Kopsiro Centre.
Since independence, Mt. Elgon constituency electorates has elected five different Members of the National Assembly (MPs). Daniel Moss was the pioneer MP in 1963, while Fred Chesebe Kapondi is the incumbent. It is worthy also noting that Mt. Elgon is the only constituency created at independence that has never been subdivided to create more electoral area units, an issue that has disenfranchised its electorate. This was witnessed by the recent call for ELEXIT (Elgon Exit from Bungoma County), a memorandum that was received at the SENATE during the highs of BBI.
The constituency has six wards, all electing Members of County Assembly (MCAs) for the Bungoma County Assembly.
