Hasseltia is a genus of flowering plants in the family Salicaceae. It contains four species of small to medium-sized trees native to the neotropics, ranging from Mexico south to Brazil and Bolivia. ^[1] The genus is named for the Dutch physician and botanist Johan Conrad van Hasselt.

Hasseltia is unique among Salicaceae in that the species have pseudo-axile placentation, compound umbellate inflorescences, and a pair of glands embedded in the base of the leaf blades. ^[1] Formerly placed in the heterogeneous family Flacourtiaceae, ^[2] Hasseltia is now classified in Salicaceae, along with close relatives Pleuranthodendron and Macrothumia , with which they are commonly confused. ^{[1] [3] [4]}
