In geometry, the Hebesphenomegacorona is one of the
Johnson solids ("J"₈₉).It is one of the elementary Johnson solids that do not arise from "cut and paste" manipulations of the Platonic and Archimedean solids. It has 21 faces, 18 triangles and 3 squares, 33 edges, and 14 vertices.

The 92 Johnson solids were named and described by Norman Johnson in 1966.
