Epidendrum radicans is a species of orchid native to Central America and northern South America. Common names include ground-rooting epidendrum, fire-star orchid, crucifix orchid, rainbow orchid, and reed-stem epidendrum.

The diagnostic characteristic of E. radicans is its tendency to sprout roots all along the length of the stem; other crucifix orchids only produce roots near the base. It is a frequent roadside weed at middle elevations in Central America. Its common name 'crucifix orchid' refers to the tiny cross-shaped labellum in the centre of the flower.
