The marsh tchagra was described by the German ornithologist Gustav Hartlaub in 1858 and given the binomial name Telephonus minutus.[3] The species is now placed in the monotypic genus Bocagia that was introduced by the English ornithologist George Ernest Shelley in 1894.[4]

Three subspecies are recognised.[5]
