Described as Vireo nanus Nelson 1898; type locality Queréndaro, Michoacán, Mexico. The name nanus is preoccupied in Vireo by Empidonax nanus Lawrence = Vireo nanus (Flat-billed Vireo) (Bond 1934). Bond (1936) proposed the replacement name Vireo nelsoni. Presumably Bond proposed the name nelsoni in honor of E.W. Nelson.

There is no comprehensive phylogeny for Vireo. Investigations of relationships within Vireo on the basis of starch gel electrophoresis of protein coding loci (Johnson et al. 1988) and from phylogenetic analysis of mitochondrial DNA sequence data (Murray et al. 1994) did not include representatives of nelsoni. Mayr and Short (1970) considered nelsoni to belong to a species group composed of Vireo griseus (White-eyed Vireo), Vireo crassirostris (Thick-billed Vireo), Vireo modestus (Jamaican Vireo), Vireo caribaeus (San Andres Vireo), Vireo gundlachii (Cuban Vireo), Vireo pallens (Mangrove Vireo), Vireo belli (Bell's Vireo), Vireo vicinior (Gray Vireo), Vireo latimeri (Puerto Rican Vireo), and Vireo bairdi (Cozumel Vireo). Sibley and Monroe (1990), however, considered nelsoni to form a superspecies with Vireo atricapilla (Black-capped Vireo), and some authors (Barlow 1980, Phillips 1991) even have suggested that nelsoni and atricapilla could be conspecific.
