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