Holodiscus discolor, commonly known as ocean spray or oceanspray, creambush, or ironwood, is a shrub of western North America.

Its alternate leaves are small, 5–9 centimetres (2–3+1⁄2 inches) long and 4–7 cm (1+1⁄2–3 in) broad, lobed, juicy green when new.

It is found in a variety of habitats, from moist coastal forests to drier, cooler mountains of inland California.

In the California black oak woodland plant community, common understory associate species include Toxicodendron diversilobum (Western poison-oak), Heteromeles arbutifolia (toyon), and Dryopteris arguta (coastal wood fern).

Several First Nations, such as the Stl'atl'imx, would steep the berries in boiling water to use as a treatment for diarrhea, smallpox, chickenpox and as a blood tonic.
