In geometry, the trigonal trapezohedron or deltohedron is the first in an infinite series of face-uniform polyhedra which are dual to the antiprisms. It has six faces which are congruent rhombi.

Trigonal trapezohedrons are a subset of the rhombohedrons. The cube is a special case with square faces.
