The Spinulosida are an order of sea stars containing at least 120 species in seven genera and two families.

Spinulosids completely lack pedicellariae and have a delicate skeletal arrangement. Their name comes from the presence of numerous low spines on the aboral (upper) surface.[2] No fossil spinulosids have yet been found.[3]

The following family is recognised by the World Register of Marine Species:[1]

Echinasteridae Verrill, 1870
