The red-winged prinia was described by the Scottish naturalist William Jardine in 1849 under the binomial nameDrymoica erythroptera. The type locality is West Africa. The specific epitheterythroptera comes from the Ancient Greek eruthros for "red" and -pteros, "-winged".
P. e. rhodoptera (Shelley, 1880) – Kenya to eastern Zimbabwe and Mozambique
Most taxonomists place this species in the genus Prinia rather than in its own monotypic genus Heliolais. Support for this alternative placement is provided by a molecular phylogenetic study of the Cisticolidae published in 2013 that found that the red-winged warbler was closely related to the prinias.
