The Sikkim wedge-billed babbler or blackish-breasted babbler (Stachyris humei) is a species of bird in the Old World babbler family (Timaliidae). It is named for the Indian state of Sikkim.
It inhabits the understorey of broadleaf evergreen forest and bamboo at 900–1,950 m, favouring westward facing slopes in Bhutan. It occupies lower elevations only during the winter. It occurs in small parties and feeds on insects, particularly woodlice and boring beetles.
