A **rhombic pyramid** is a pyramid based on a rhombus. It has 1 rhombus base and 4 identical scalene triangles as faces.

Rhombic pyramids occur as the cells of duals of some prismatic uniform polychora, particularly ones that are prisms of polyhedra with rectangular vertex figures, since the rectangle is the dual of the rhombus.
