Hoya oligantha is a Hoya species native to New Guinea, known for its compact foliage and relatively few-flowered inflorescences.

Hoya oligantha was collected by Rudolf Schlechter in the Torricelli Mountains of New Guinea on September 13, 1909. His collection was numbered 20176, and the species was formally published in 1913.

The name “oligantha” refers to the plant’s few-flowered habit — an appropriate distinction for a Hoya that produces much smaller flower clusters than the large umbels seen in many other species.

Recent botanical work continues to recognize Hoya oligantha as a distinct New Guinea species. Modern references place it among the smaller-flowered Hoyas of the region, with individual flowers reaching roughly 2.5–3 cm across.
