Radermachera is a genus of about 17 species of flowering plants in the family Bignoniaceae, native to southeastern Asia. They are evergreen trees reaching 5–40 m tall, with bipinnate to tripinnate leaves, and panicles of large bell-shaped, white, pink, pale purple or yellow flowers 5–7 cm diameter.

The genus is named after Jacob Cornelis Matthieu Radermacher, the 18th century Dutch naturalist who cataloged much of the flora of Java and Sumatra.
