Horizontal navelwort ("Umbilicus horizontalis") is a fleshy, perennial flowering plant in the stonecrop family Crassulaceae (in the genus "Umbilicus") found in the Mediterranean and Bulgaria, as well as Bali, New Zealand, and the Canary Islands.

Horizontal navelwort grows to an average of 25 cm (10 in) high. The thickly clustered, bell-shaped flowers are pale green and grow in a raceme perpendicular to the spike, unlike common navelwort, whose flowers droop (thus the title "horizontal").

The plant often grows on shady walls or in damp rock crevices that are sparse in other plant growth, where its succulent, dark green leaves develop in rosettes that are about 7 cm (3 in) wide. Horizontal navelwort is similar to common navelwort in many respects, but is significantly thicker.
