Ash is the name of three very distinct group of trees. In America and Europe, "ash" generally refers to trees of the Genus Fraxinus. In Great Britain, "ash" also refers to the mountain ash or Rowan, Genus Sorbus. In Australia, "mountain ash" refers to a type of eucalyptus, Eucalyptus regnans, one of the tallest trees in the world (perhaps second only to the coast redwood).

The Genus Fraxinus is in the olive family (Family Oleaceae). Ashes are usually medium to large trees. Most have pinnately-compound, opposite leaves. Seeds are borne in keys, a type of fruit known as a samara.
The white ash is a particularly important timber tree in eastern North America, and is the source of wood for quality wooden baseball bats. The green ash is widely planted as a street tree in the United States. The inner bark of the blue ash has been used as a source for a blue dye.

In Norse mythology, the World Tree, Yggdrasil, was an ash tree, and the man, Ask, was formed from an ash tree (the first woman was made from alder). Elsewhere in Europe, snakes were said to be repelled by ash leaves or a circle drawn by an ash branch. Irish folklore claims that shadows from an ash tree damage crops. In Cheshire, it is said that ash could be used to cure warts or rickets.
