Juniperus standleyi is a species of juniper native to Guatemala and the adjacent extreme southeast of Mexico (Volcán Tacaná in Chiapas), where it occurs at elevations of 3,000-4,250 m. Its local common names include huitó, cipres, and huitum.
Juniperus standleyi is an evergreen coniferous shrub or small to medium-sized tree growing to 5-15 m (rarely 20 m) tall. The leaves are of two forms, juvenile needle-like leaves 5-7 mm long on seedlings and occasionally (regrowth after browsing damage) on adult plants, and adult scale-leaves 1-1.5 mm long on older plants; they are arranged in decussate opposite pairs or whorls of three.
The cones are globose, berry-like, 6-9 mm diameter, blue-black with a thin pale waxy coating, and contain three to six seeds; they are mature in about 18 months. The male cones are 1.5-2 mm long, and shed their pollen in spring. It is dioecious with male and female cones on separate plants.
