星型正多面体（Kepler-Poinsot多面体）是一类凹多面体，共有四个。它们的表面均为正多边形或正星形且每个顶点都有相同数目的边连接。

In geometry, a Kepler–Poinsot polyhedron is any of four regular star polyhedra.

They may be obtained by stellating the regular convex dodecahedron and icosahedron, and differ from these in having regular pentagrammic faces or vertex figures.
