Juniperus horizontalis, the creeping juniper or creeping cedar, is a low-growing shrubby juniper native to northern North America, throughout most of Canada from Yukon east to Newfoundland, and in some of the northern United States.

Living up to both its scientific and common names, the species reaches only 10-30 centimetres (3+7⁄8-11+3⁄4 in) tall but often spreading several metres wide. The shoots are slender, 0.7-1.2 millimetres (1⁄32-1⁄16 in) diameter. The leaves are arranged in opposite decussate pairs, or occasionally in whorls of three; the adult leaf blades are scale-like, 1-2 mm long (to 8 mm on lead shoots) and 1-1.5 mm (1⁄32-1⁄16 in) broad, and derive from an adnate petiole. The juvenile leaves (on young seedlings only) are needle-like, 5-10 mm (3⁄16-3⁄8 in) long. The cones are berry-like, globose to bilobed, 5-7 mm (3⁄16-9⁄32 in) in diameter, dark blue with a pale blue-white waxy bloom, and contain two seeds (rarely one or three); they usually have a curved stem and are mature in about 18 months. The male cones are 2-4 mm (3⁄32-5⁄32 in) long, and shed their pollen in early spring. It is dioecious, producing cones of only one sex on each plant.

It is closely related to Juniperus virginiana, and often hybridizes with it where their ranges meet in southern Canada. Hybrids with Juniperus scopulorum also occur.
