在几何学中，七面体是指由7个面组成的多面体，而边长全部等长的七面体是五角柱，有时会称为半正七面体。
常见的七面体有六角锥、五角柱、正三角锥柱、Szilassi多面体等多面体。
再所有七面体中，只有正三角锥柱是詹森多面体。

A heptahedron (plural: heptahedra) is a polyhedron having seven sides, or faces.
A heptahedron can take a surprising number of different basic forms, or topologies. Probably most familiar are the hexagonal pyramid and the pentagonal prism. Also notable is the tetrahemihexahedron, whose seven equilateral triangle faces form a rudimentary projective plane. No heptahedra are regular.
