An n-agonal bifrustum is a polyhedron composed of three parallel planes of n-agons, with the middle plane largest and usually the top and bottom congruent.

It can be constructed as two congruent frustum combined across a plane of symmetry, and also as a bipyramid with the two polar vertices truncated.
