Olea (pronounced /ˈoʊliːə/) is a genus of about 20 species in the family Oleaceae, native to warm temperate and tropical regions of southern Europe, Africa, southern Asia and Australasia. They are evergreen trees and shrubs, with small, opposite, entire leaves. The fruit is a drupe.

For humans, the most important species is by far the Olive (Olea europaea), native to the Mediterranean region. O. paniculata is a larger tree, attaining a height of 15-18 m in the forests of Queensland, and yielding a hard and tough timber. The yet harder wood of the Black Ironwood O. laurifolia, an inhabitant of Natal, is important in South Africa.
