In geometry, the dodecagonal prism is the tenth in an infinite set of prisms, formed by square sides and two regular dodecagon caps.

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

Use

It is used in the construction of two prismatic uniform honeycombs:

Omnitruncated triangular-hexagonal prismatic honeycomb {{CDD	6\|node_1\|3\|node_1\|2\|node_1\|infin\|node}	Truncated hexagonal prismatic honeycomb {{CDD>node_1\|6\|node_1\|3\|node\|2\|node_1\|infin\|node}}
