Meridiastra is a genus of star fish in the family Asterinidae. The genus is found in the Indian and Pacific Oceans, with most records from the waters around Australia. They occur in shallow waters down to a depth of about 59 m (194 ft). Meridiastra are morphologically similar to the Atlantic genus Asterina. They are also phylogenetically close and possibly sister genera.
