Hypericum forrestii is a species of flowering plant in the family Hypericaceae native to Yunnan and Sichuan Provinces in China, and northeastern Burma. It is a semi-evergreen shrub growing to 1.2 m (4 ft) tall by 1.5 m (5 ft) broad, with oval leaves which turn red in autumn, and bowl-shaped yellow flowers with prominent stamens in late summer.[1][2]

Common names include Forrest's tutsan[3] and Forrest's St. John's wort.

It has been recorded as a garden escape in locations in the British Isles,[4] and as an invasive species.[5] It may be under-recorded due to confusion with other hypericums such as Hypericum 'Hidcote'.[4]

This plant has gained the Royal Horticultural Society's Award of Garden Merit.[6] It was named in honour of George Forrest (1873-1932), who discovered it.
