Jeleen Yatta Ntanye, more commonly known as Jelen, Jeléen, or Bemoim,[1] was a buumi of the Jolof Empire who attempted to take control of the state with help from the Portuguese in the late 15th century.

[5][6] He played an important role in governing the empire, with the Buurba occupied with personal pleasures, and is credited in oral history as the first to establish a system of 'alkaldes' who served as customs agents.

[7][6] He moved his seat, or perhaps that of the whole empire, closer to the coast in order to better take advantage of the opportunities arising from the Portuguese trade that had begun a few decades earlier.

Bemoim, a term coming from his title 'Bumi' in Wolof,[9][10] received an envoy from Portugal sent to address the dispute.

[13] They agreed that the Portuguese would send a force to Jolof to set up a fort and trading post at the mouth of the Senegal river and restore Jelen to power.
