Acampe, abbreviated as Acp in horticultural trade, is a genus of monopodial, epiphytic vandaceous species of orchids, distributed from tropical Asia from India, eastwards to China and southwards to Malaysia, and the Philippines as well as from tropical Africa, Madagascar and islands of the Indian Ocean. The name Acampe was derived from the Greek word akampas, meaning "rigid", referring to the small, brittle, inflexible flowers.

Acampe produce slow-growing, medium-sized vines that form very large vegetative masses in nature. They are noted for their thick, leathery, distichous leaves. They produce fragrant small to medium-sized yellow flowers, barred with orange or red stripes, in a few to many-flowered racemose inflorescence. The brittle sepals and petals look alike. The ear-shaped, fringed, white labellum (lip) is saccate (sac-shaped) or has a spur, and has red markings at its base. The fleshy column is short and has two waxy pollinia.

Due to their large size and small flowers, they are rarely cultivated.
