冷杉属（学名：Abies），又稱樅，是松科下的一个属，约40种。冷杉属植物原产于北美、中美、亚洲、欧洲和非洲北部。冷杉的叶与松科其他属植物不同。其叶针状，直接生于枝上，叶基部形似吸杯，落叶后枝上留下环形叶痕。毬果垂直单生，成熟后鳞片脱落，但穗状轴在枝上宿存。每片薄而呈圆形的果鳞上著生两粒具宽翅的种子。 参考文献 ^ Schorn, Howard; Wehr, Wesley.

Firs are evergreen coniferous trees belonging to the genus Abies () in the family Pinaceae. There are approximately 48–65 extant species, found on mountains throughout much of North and Central America, Eurasia, and North Africa. The genus is most closely related to Keteleeria, a small genus confined to eastern Asia.
They are tall trees that can be distinguished from other members of the pine family by the way in which their needle-like leaves are attached singly to the branches with a circular base, and by their cones, which, like those of cedars, stand upright on the branches like candles and disintegrate at maturity.
