Patiriella regularis, the New Zealand common cushion star, is a sea star of the family Asterinidae, native to New Zealand.

It is one of New Zealand's most common rocky shore starfish.

[2] They were introduced into waters in south east Tasmania, where they have become well established.

A genetic variance is found in P. regularis from the North and South of New Zealand.

Geographic barriers, and coastal upwellings might keep various types of P. regularis from being able to spread or comingle.
