The black-and-white mannikin (Spermestes bicolor) also black-and-white munia or red-backed mannikin, is a species of estrildid finch, widely occurring throughout the African tropical rainforest.

The status of the species is evaluated as least concern.

[2] The black-and-white mannikin was formally described in 1843 by the British zoologist and collector Louis Fraser from a specimen collected near Cape Palmas in Liberia.

[3][4] The black-and-white mannikin is now one of the four species placed in the genus Spermestes that was introduced in 1837 by William Swainson.

[5][6] Four subspecies are recognised:[6] The subspecies S. b. woltersi and S. b. nigriceps have sometimes been considered as a separate species, the red-backed mannikin.
