In geometry, the Snub disphenoid is one of the Johnson solids (J84). It is a three-dimensional solid that has equilateral triangles only as faces. It is a deltahedron. It is not a Platonic solid because some vertices have 4 faces meeting and others have 5. It is one of the elementary Johnson solids that do not arise from "cut and paste" manipulations of the Platonic and Archimedean solids.
