在几何学中，五角化十二面体是卡塔兰立体的一种，它的对偶多面体是截角二十面体或半正三十二面体。

五角化十二面体是五边形五边各加一个等腰三角形拼成的正十边形在立体几何中的推广。

当每面叠上的五角锥的高不是十二面体外置球到面的距离时，就会有如下情况:

In geometry, a pentakis dodecahedron or kisdodecahedron is a dodecahedron with a pentagonal pyramid covering each face; that is, it is the Kleetope of the dodecahedron. This interpretation is expressed in its name. There are in fact several topologically equivalent but geometrically distinct kinds of pentakis dodecahedron, depending on the height of the pentagonal pyramids. These include:
