A spherical reflector is a reflector shaped like a portion of a sphere, so that light (or other electromagnetic radiation such as radio waves) from a point-source located at the virtual centre point of the sphere will reflect off the mirrored surface and back through the centre point of the sphere.

Spherical reflectors suffer from spherical aberration, since not all reflected paths focus exactly on the center point.
