The yellow-browed shrike-vireo was previously classified as a subspecies of the green shrike-vireo (V. pulchellus) and the two form a superspecies. Its further taxonomy is not settled. The IOC and AviList treat it as a monotypic species. The Clements taxonomy and BirdLife International's Handbook of the Birds of the World assign it two subspecies, the nominate V. e. eximius and V. e. mutabilis.
