Elaeagnaceae, the oleaster family, is a plant family of the order Rosales comprising small trees and shrubs, native to temperate regions of the Northern Hemisphere, south into tropical Asia and Australia. The family has 45-50 species in three genera.

They are commonly thorny, with simple leaves often coated with tiny scales or hairs. Most of the species are xerophytes (found in dry habitats); several are also halophytes, tolerating high levels of soil salinity.

The Elaeagnaceae often harbor nitrogen-fixing actinomycetes of the genus Frankia in their roots, making them useful for soil reclamation.[2] This characteristic, together with their production of plentiful seeds, often results in Eleagnaceae being viewed as weeds.
