Fraxinus americana (White Ash or American Ash) is a species of Fraxinus native to eastern North America found in mesophytic hardwood forests from Nova Scotia west to Minnesota, south to northern Florida, and southwest to eastern Texas.

The name White Ash derives from the glaucous undersides of the leaves. It is similar in appearance to the Green Ash, making identification difficult. The lower sides of the leaves of White Ash are lighter in color than their upper sides, and the outer surface of the twigs of White Ash may be flaky or peeling. Green Ash leaves are similar in color on upper and lower sides, and twigs are smoother. Also, these species tend to occupy different habitat niches, with White Ash found in moist upland sites and Green Ash in wet forests of floodplains or swamps, although there is some overlap in habitat distribution.

It is widely grown as an ornamental tree. Cultivars selected for superior fall color include 'Autumn Applause' and 'Autumn Purple'.

Other names occasionally used for the species include Biltmore ash, Biltmore white ash and cane ash.
