The '''Orbison illusion''' is an [[optical illusion]] that was first described by the psychologist William Orbison (1909 – 1981) in 1939. It consists of a figure placed over a background of concentric circles or radial lines. The bounding rectangle and inner square both appear distorted in the presence of the circles or radiating lines. The background gives the impression that there is some sort of perspective; as a result, a distorted shape is seen. This is a variant of the [[Hering illusion|Hering]] and [[Wundt illusion]]s.{{cn|date=October 2015}} |

The Orbison illusion (or Orbison's illusion) is an optical illusion first described by American psychologist William Orbison (1912–1952)[1] in 1939.
The illusion consists of a two dimensional figure, such as a circle or square, superimposed over a background of radial lines or concentric circles. The result is an optical illusion in which both the figure and the rectangle which contains it appear distorted; in particular, squares appear slightly bulged, circles appear elliptical, and the containing rectangle appears tilted.[2]
