Tybalt is a character in William Shakespeare's play Romeo and Juliet. He is the son of Lady Capulet's brother, Juliet's short-tempered first cousin, and Romeo's rival. Tybalt shares the same name as the character Tibert / Tybalt "the prince of cats" in the popular story Reynard the Fox, a point of mockery in the play. Mercutio repeatedly calls Tybalt "prince of cats", in reference to his sleek, yet violent manner.

Romeo and Juliet is a tragedy written by William Shakespeare early in his career about the romance between two Italian youths from feuding families. It was among Shakespeare's most popular plays during his lifetime and, along with Hamlet, is one of his most frequently performed. Today, the title characters are regarded as archetypal young lovers.
