Margaret de Quincy, 2nd Countess of Lincoln suo jure (c. 1206 – March 1266) was a wealthy English noblewoman and heiress having inherited in her own right the Earldom of Lincoln and honours of Bolingbroke from her mother Hawise of Chester, received a dower from the estates of her first husband, and acquired a dower third from the extensive earldom of Pembroke following the death of her second husband, Walter Marshal, 5th Earl of Pembroke. Her first husband was John de Lacy, 2nd Earl of Lincoln, by whom she had two children. He was created 2nd Earl of Lincoln by right of his marriage to Margaret.
