Jean de Béthencourt (1362–1425) is a French explorer who in 1402 leads an expedition to the Canary Islands, landing first on the north side of Lanzarote.

From here he conquers for Castile the islands of Fuerteventura (1405) and Hierro, ousting their local chieftains (majos and bimbaches, ancient peoples).

Béthencourt receives the title King of the Canary Islands but he recognizes King Henry III of Castile, who has provided aid during the conquest, as his overlord.
