Vanilla phaeantha, common name leafy vanilla[1] or oblong-leaved vanilla,[1] is a plant species known to occur in the wild, only on the islands of Trinidad and Cuba, and also in Collier County, Florida.

It occurs in cypress swamps and hammocks at elevations of less than 20 m (67 feet).

[1] Vanilla phaeantha has persistent, leathery, flat leaves up to 15 cm long, hence about the same length as the internodes or slightly shorter.

Sepals and petals are green, leathery and rigid except for the yellow to cream-colored lip.

Fruits are cylindrical, up to 10 cm (4 inches) long and 1 cm (0.4 inches) in diameter.
