Alloceramaster is a genus of sea stars in the family Goniasteridae.
The genus Alloceramaster was described by Mah in 2025 to include Ceramaster-like taxa characterized by the presence of heteromorphic granules around the radial regions, specifically those with elongate to angular peripheral granules and more rounded to polygonal central granules on triangular or polygonal shaped plates, along with a bare spot on the superomarginal plate surface. It also differs from Sphaeriodiscus by lacking enlarged penultimate or antipenultimate superomarginal plates and by having fewer marginal plates per interradius with a bald or sparsely granular superomarginal surface.[1]
