Oeceoclades flavescens is a terrestrial orchid species in the genus Oeceoclades that is endemic to northeastern Madagascar. It was first described by the French botanists Jean Marie Bosser and Philippe Morat in 2001. The type specimen was collected in 1954 from the wet undergrowth of a coastal forest near Maroantsetra; it is the only known collection of this species. The specific epithet flavescens refers to the pale yellow flowers.
