In geometry, the Hebesphenomegacorona is one of the Johnson solids (J89). 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.
