Judith Quiney (baptised 2 February 1585 – 9 February 1662), née Shakespeare, was the younger daughter of William Shakespeare and Anne Hathaway and the fraternal twin of Shakespeare's only son Hamnet Shakespeare. She married Thomas Quiney, a vintner of Stratford-upon-Avon. The circumstances of the marriage, including Quiney's misconduct, may have prompted the rewriting of Shakespeare's will. Thomas was struck out, while Judith's inheritance was attached with provisions to safeguard it from her husband. The bulk of Shakespeare's estate was left, in an elaborate fee tail, to his elder daughter Susanna and her male heirs.
Judith and Thomas Quiney had three children. By the time of Judith Quiney's death, she had outlived her children by many years. She has been depicted in several works of fiction as part of an attempt to piece together unknown portions of her father's life.
