Rhododendron thayerianum (反边杜鹃) is a rhododendron species native to western Sichuan in China, where it grows at elevations of 2,600–3,000 m (8,500–9,800 ft).

It is an evergreen shrub that grows to 3–4 m (9.8–13.1 ft) in height, with leathery leaves that are narrowly oblanceolate, and 9–17 × 1.5–2.5 cm in size.

The flowers are white, sometimes deeply flushed pink on the outside along the petal ridges, or pink.

It flowers quite late in the season, in June and July.
