The tepui goldenthroat (Polytmus milleri) is a species of hummingbird in the subfamily Polytminae, the mangoes.

The female is smaller than the male and has dull white underparts heavily dotted with golden-green, especially on the breast.

On these isolated flat-topped mountains it inhabits the edge of cloudforest and scrublands with scattered trees at elevations between 1,300 and 2,200 m (4,300 and 7,200 ft).

[7] The tepui goldenthroat is "trap-line" feeder, visiting a circuit of a variety of flowering plants for nectar.

[7] The IUCN has assessed the tepui goldenthroat as being of Least Concern, though its population size and trend are unknown.
