In geometry the net of a polyhedron is an arrangement of edge-joined polygons in the plane which can be folded (along edges) to become the faces of the polyhedron. Polyhedral nets are a useful aid to the study of polyhedra and solid geometry in general, as they allow for models of polyhedra to be constructed from material such as thin cardboard.

For any given polyhedron that is unfolded into a net, many different equivalent nets can be formed depending on the choices of which edges are joined and which are separated.
