Cedar is part of the English common name of many trees and other plants, particularly those of the genus Cedrus.

Some botanical authorities consider the Old-World Cedrus the only "true cedars".^[1][2] Many other species worldwide with similarly aromatic wood, including several species of genera Calocedrus, Thuja, and Chamaecyparis in the Pacific Northwest of North America, are referred to as "false cedars".^[3]
