The dodecagonal antiprism is a prismatic uniform polyhedron. It consists of 24 triangles and 2 dodecagons. Each vertex joins one dodecagon and three triangles. It is an antiprism based on a dodecagon.

Representations
A dodecagonal antiprism has the following Coxeter diagrams:


 * s2s24o (alternated icositetragonal prism)
 * s2s12s (alternated didodecagonal prism)
 * xo12ox&#x (bases considered separately)
