Compsolechia crescentifasciella is a moth of the Gelechiidae family. It was described by Chambers in 1874. It is found in North America, where it has been recorded from Texas. Adults are ash grey, microscopically dusted with brown. There is a crescentic, very indistinct pale fascia at the beginning of the ciliae, very concave towards the base of the wing. There are also one or two minute dark spots on the disc, and one at its apex.
