Acer macrophyllum, the bigleaf maple or Oregon maple, is a large deciduous tree in the genus Acer. It is native to western North America. In addition to uses by animals, it is of some culinary and woodworking interest.
Bigleaf maple can grow up to 48 metres (158 feet) tall, but more commonly reaches 15–20 m (50–65 ft) tall and 90–120 centimetres (35–47 inches).
The bigleaf maple has the largest leaves of any maple, typically 15–30 cm (6–12 in) across with five deeply incised palmate lobes, with the largest running to 61 cm (24 in).
