George Richard Wilson Knight (1897-1985) was an English literary critic and academic, known particularly for his interpretation of mythic content in literature, and his essays The Wheel of Fire on Shakespeare's drama. He was also an actor and theatrical director, and considered an outstanding lecturer.

He was educated at Dean Close School and Dulwich College, and after serving as a dispatch rider in World War I, at St Edmund Hall, Oxford. He went into teaching; his first academic post was at Trinity College, Toronto in 1931. He taught at Stowe School from 1941 to 1946 and then was Reader in English Literature at the University of Leeds, where he became a professor in 1956.

The classical scholar William Francis Jackson Knight (1895-1964), of whom he wrote a biography, was his brother.

In a literary context, the Wheel of Fire may refer to the chain of tortuous or dire consequences that result from a single action.

The Wheel of Fire is part of the Aristotelian reading of a tragedy (e.g. plays), which includes the central flaw within a character. In Shakespeare's tragedy Othello, the flaw in Othello himself is his vulnerability to jealousy and his tendency to believe Iago, who is manipulating Othello into believing his wife is unfaithful. As a result of this flaw Othello loses a loyal friend, murders his wife, and is driven insane before eventually committing suicide. In this scenario the Wheel of Fire begins with the action of Othello trusting Iago and consequently the other events occur.

The Wheel of Fire is most commonly applied to the protagonist within a tragedy (i.e. the hero) and may aim to provoke sympathy from the audience when the hero falls from grace (this purging of emotions is known as catharsis), though it also adds dramatic interest to the performance.

The Wheel of Fire is also the title of G. Wilson Knight's book on Shakespearean tragedy.
