Maoricolpus is a genus of gastropod molluscs in the family Turritellidae, known as the New Zealand screw shells. The shells are rather large and solid, with many more or less straight-sided whorls. The protoconch has about 2½ smooth whorls, increasing slowly from a small nucleus, and set somewhat mucronately on the rapidly increasing first neanic whorl. The outer lip is thin and sinuous, with a broadly concave median sinus.

The genus is endemic to New Zealand.
