In geometry, the truncated hexagonal trapezohedron is the fourth in an infinite series of truncated trapezohedra.

It has 12 pentagon and 2 hexagon faces.

It can be constructed by taking a hexagonal trapezohedron and truncating the polar axis vertices.

The Weaire–Phelan structure contains another form of this polyhedron that has D2d symmetry and is a part of a space-filling honeycomb along with an irregular dodecahedron.
