Bulbophyllum medusae is an epiphytic orchid native to lowland and hill forests of Thailand, Peninsular Malaysia, Sumatra, and Borneo. It is distinguished by its rounded inflorescences bearing many small flowers with long, filamentous lateral sepals that radiate outward in loose strands.

The species was first described as Cirrhopetalum medusae by John Lindley in 1842, and transferred to Bulbophyllum by Heinrich Gustav Reichenbach in 1861.
