In geometry, the decagonal prism is the eighth in an infinite set of prisms, formed by ten square side faces and two regular decagon caps. With twelve faces, it is one of many nonregular dodecahedra.

If faces are all regular, it is a semiregular polyhedron.

Uses

The decagonal prism exists as cells in two four-dimensional uniform polychora:
