The pentagonal bifrustum or pentagonal truncated bipyramid is the third in an infinite series of bifrustum polyhedra. It has 10 trapezoid and 2 pentagonal faces. It is the dual of the Johnson solid, elongated pentagonal dipyramid.

This polyhedron can be constructed by taking a pentagonal dipyramid and truncating the polar axis vertices, making is into two end-to-end frustums.
