Grand Cayman Thrush was described in the genus Mimocichla (Cory 1886a) which differed from Turdus in a number of features, including plumage coloration, a graduated to rounded tail with strong white tail corners, and several measurement ratios such as tarsus/wing ratio. Red-legged Thrush (Turdus plumbeus) (in the past considered several species) was also assigned to this genus (e.g., Ridgway 1907: 80-86, Bond 1956: 128; Johnston 1969). These species are now included within genus Turdus and relatively closely related to e.g., American Robin, Turdus migratorius (Voelker et al. 2007).

It has been hypothesized that Grand Cayman Thrush was derived from a relative in Jamaica that however went extinct before discovery (Bangs 1916, Bond 1956). Among known species, the closest relative seems undoubtedly to be Red-legged Thrush, and among still living species the next closest relative should be White-chinned Thrush, Turdus aurantius (Voelker et al. 2007).
