Acer macrophyllum (Bigleaf Maple or Oregon Maple) is a large deciduous tree in the genus Acer.

It grows to be up to 35 m tall, but more commonly 15 m to 20 m tall. It is native to western North America, mostly near the Pacific coast, from southernmost Alaska south to southern California. Some stands are also found inland in the foothills of the Sierra Nevada mountains of central California, and a tiny population occurs in central Idaho.

Bigleaf Maple flowers and foliage

It has the largest leaves of any maple, typically 15-30 cm across, with five deeply-incised palmate lobes, with the largest running to 61 cm.

The flowers are produced in spring in pendulous racemes 10-15 cm long, greenish-yellow with inconspicuous petals. The fruit is a paired winged samara, each seed 1-1.5 cm diameter with a 4-5 cm wing.

Bigleaf maple can form pure stands on moist soils in proximity to streams, but are generally found within riparian hardwood forests or dispersed, (under or within), relatively open canopies of conifers, mixed evergreens, or oaks (Quercus spp.).. In cool and moist temperate mixed woods they are one of the dominant species .
