Thuja is a genus of coniferous trees in the Cupressaceae (cypress family). There are five species in the genus, two native to North America and three native to eastern Asia.[3][4] The genus is monophyletic and sister to Thujopsis.

They are commonly known as arborvitaes (from Latin for tree of life) or thujas; several species are widely known as cedar but because they are not true cedars (Cedrus) it has been recommended to call them redcedars or whitecedars
