Leiothrix is a genus of passerine birds in the family Leiothrichidae.

They belong to a clade also containing at least the liocichlas, barwings, minlas and sibias.

The sibias are possibly their closest living relatives.

The genus Leiothrix was introduced in 1832 by the English naturalist William Swainson with the red-billed leiothrix as the type species.

Their delicate colors and accomplished song make them popular cagebirds.
