Hippolais is a genus of tree warbler in the family Acrocephalidae.

It is sometimes associated with the genus Iduna.

[2] The genus name Hippolais is from Ancient Greek hupolais, as misspelt by Linnaeus.

It referred to a small bird mentioned by Aristotle and others and may be onomatopoeic or derived from hupo,"under", and laas, "stone".
