Port Orford Cedar, an evergreen tree native to the coast of southern Oregon and northern California. It is also called Oregon cedar, Lawson cypress, and false cypress. It is not a cedar, but is related to the true cypress. In many parts of the United States and Europe it is commonly used as an ornamental tree. The many cultivated varieties grow about 80 feet (24 m) tall and have a columnar or pyramidal shape, with fernlike, drooping foliage that may be bright green, bluish, or silvery.

As a forest tree the Port Orford cedar grows about 200 feet (60 m) tall. Its durable wood was once widely used for floors and in furniture; it is now used mainly to make arrow shafts.

Port Orford cedar is Chamaecyparis lawsoniana of the cypress family, Cupressaceae.
