Hoya macgillivrayi, commonly known as red hoya or Macgillivray's wax flower,[2] is a species of vine endemic to Cape York Peninsula in Queensland, and has egg-shaped to lance-shaped leaves and racemes of dark reddish-pink flowers, sometimes with a white centre, and a reddish-pink corona.

Hoya macgillivrayi is a vine with stems less than 20 mm (0.79 in) in diameter and containing white, milky sap.

[3][4][5][6] Hoya macgillivrayi was first formally described in 1914 by Frederick Manson Bailey in the Queensland Agricultural Journal from specimens collected by William MacGillivray near "Claudie River, Lloyd Bay".

[6] This species of Hoya grows in rainforest and monsoon forest in the Iron and McIlwraith Ranges on Cape York Peninsula, from sea level to 450 m (1,480 ft).

[2] This species requires a loose, friable peaty soil mixture and good drainage.
