Lalage is a genus of passerine birds belonging to the cuckooshrike family Campephagidae, many of which are commonly known as trillers.

They build a neat cup-shaped nest high in a tree.

Most species are fairly common but the Samoan triller is considered to be near threatened and the Norfolk Island subspecies of the long-tailed triller has become extinct.

The genus Lalage was introduced in 1826 by the German zoologist Friedrich Boie to accommodate a single species, Turdus orientalis Gmelin, JF, 1788, a junior synonym of Turdus niger Pennant, 1781, the pied triller.

A molecular phylogenetic study published in 2010 found that the species form part of the clade that contain members of the genus Lalage.
