Juniperus foetidissima, with common names Foetid juniper or Stinking juniper, is a juniper tree species in the Cupressaceae family.
A number of notably large specimens are specially protected in Turkey; the largest is the Aslanardıçı ("Lion Juniper"), 25 m tall and 3.38 m trunk diameter, estimated to be 1,700 years old (Boscawen 1994).
The leaves are of two forms, juvenile needle-like leaves 8-10 mm long on seedlings and re-growth after branch damage, and adult scale-leaves 2-3 mm long on older plants. It is largely dioecious with separate male and female plants, but some individual plants are monoecious, producing both sexes.
The cones are berry-like, 7-13 mm in diameter, Blue-black with a whitish waxy bloom, and contain 1-2 (rarely 3) seeds; they are mature in about 18 months. The male cones are 2-3.5 mm long, and shed their pollen in early spring.
It often occurs together with Juniperus excelsa, being distinguished from it by its thicker shoots 1.2-2 mm diameter (0.7-1.3 mm diameter in J. excelsa), and green, rather than grey-green, leaves. The crushed foliage has a strong foetid smell, from which the species gets its name.
