In geometry, the square cupola, sometimes called lesser dome, is one of the Johnson solids (J4). It can be obtained as a slice of the rhombicuboctahedron. As in all cupolae, the base polygon has twice as many edges and vertices as the top; in this case the base polygon is an octagon.

The following formulae for volume, surface area, and circumradius can be used if all faces are regular, with edge length a:[1]
The dual of the square cupola has 16 triangular faces:
