Tchagra is a genus of bushshrikes in the Malaconotidae family. which are closely related to the true shrikes in the family Laniidae, and were once included in that group. The marsh tchagra is sometimes placed in the monotypic genus Antichromus, and then named as blackcap bushshrike. The dark Angolan subspecies of marsh tchagra was formerly sometimes split as Anchieta's tchagra, Tchagra anchietae, named after Portuguese explorer José Alberto de Oliveira Anchieta by his zoologist compatriot José Vicente Barbosa du Bocage in 1869.
