In geometry a deltohedron is a convex polyhedron where all the faces are congruent geometric kites. The name arises from the fact that kites are also called deltoids.

Each face of a deltohedron that is also a zonohedron is a rhombus. The intersection of the class of deltohedra and zonohedra is also known as the class of rhombic polyhedra.

A deltohedron should not be confused with a deltahedron (spelled with an "a").
