Marginaster is a genus of starfish in the family Poraniidae within the order Valvatida. It was named in 1881 by Edmond Perrier, and the type species is M. pectinatus. In 1995, a fossil brittle star was given the same generic name; however, because the name was preoccupied by the starfish, the brittle star required renaming. The brittle star was renamed Marginix in 2015.
