Acer platanoides (Norway maple) is a species of maple native to eastern and central Europe and western Asia, from France east to Russia, north to southern Scandinavia and southeast to northern Iran. It is a member of the soapberry and lychee family.

Acer platanoides is a deciduous tree, growing to 20–30 m (65–100 ft) tall with a trunk up to 1.5 m (5 ft) in diameter, and a broad, rounded crown. The bark is grey-brown and shallowly grooved. Unlike many other maples, mature trees do not tend to develop a shaggy bark. The shoots are green at first, soon becoming pale brown. The winter buds are shiny red-brown.

The leaves are opposite, palmately lobed with five lobes, 7–14 cm (2 345 12 in) long and 8–20 cm or 3 147 34 in (rarely 25 cm or 9 34 in) across; the lobes each bear one to three side teeth, and an otherwise smooth margin. The leaf petiole is 8–20 cm (3 147 34 in) long, and secretes a milky juice when broken. The autumn colour is usually yellow, occasionally orange-red.

The flowers are in corymbs of 15–30 together, yellow to yellow-green with five sepals and five petals 3–4 mm (0–14 in) long; flowering occurs in early spring before the new leaves emerge. The fruit is a double samara with two winged seeds. the seeds are disc-shaped, strongly flattened, 10–15 mm (3858 in) across and 3 mm (18 in) thick. The wings are 3–5 cm (1 14–2 in) long, widely spread, approaching a 180° angle. It typically produces a large quantity of viable seeds.
