Alstonia is a widespread genus of evergreen trees and shrubs, of the family Apocynaceae. It was named by Robert Brown in 1811, after Charles Alston (1685–1760), professor of botany at Edinburgh from 1716 to 1760.

The type species Alstonia scholaris (L.) R.Br. was originally named Echites scholaris by Linnaeus in 1767.
