Revesby Abbey was a Cistercian monastery near the village of Revesby in Lincolnshire, England. The abbey was founded in 1143 by William de Roumare, Earl of Lincoln, and the first monks came from Rievaulx Abbey.

After the Dissolution of the Monasteries in the 16th century, the Abbey was demolished and a country house built. Another house was built in the mid-19th century, and is in poor condition. Unoccupied since the 1960s and previously earmarked for demolition, the house was listed on the 2023 Heritage at Risk Register issued annually by Historic England. The register recorded that, although some progress had been made in relation to the repair and renovation of the stable block, the main house remained at "serious risk".^{[citation needed]}

Revesby Abbey was founded in 1142 by William de Roumare, Earl of Lincoln, who became a monk at the abbey in his later life, and was then buried within the abbey. The first monks at the abbey were sent from Rievaulx Abbey in Yorkshire. The abbey was endowed with land at Revesby, Scithesby and Thoresby, and with the advowsons of the churches of Hagnaby and Scithesby.

During the mid-12th century, the monks of Revesby offered land in other villages to its tenants in the villages of Stichesby and Thoresby, if they would move. All 13 families left Stichesby and all 11 from Thoresby, leaving both of these settlements unpopulated. In the 14th century the abbey acquired the manor of Mareham and was granted permission to hold a weekly market and an annual fair there. In 1534 the abbey was recorded as having an income of £1287 2s. 4½d. (equivalent to £1,100,000 in 2023), and was in control of the manors of Claxby, East Keal, Hagnaby, Hameringham, Mareham-le-Fen, Mavis Enderby, Sibsey, Stickney and Toynton. However, despite this, the abbey's income appears to have been mismanaged, and in 1538 the Duke of Norfolk wrote to Thomas Cromwell to inform him the abbey was "in great ruin and decay". The abbey was dissolved c.1539.

After dissolution the former abbey passed through various hands. It was in the hands of Charles Brandon, 1st Duke of Suffolk, at the time of his death in 1545. From Brandon it passed to John Carsley and then to his son Francis Carsley. The former monastic estate was sold to William Cecil, 1st Baron Burghley, in 1575. It then passed through his family to his son: the 1st Earl of Exeter; and grandson: the 2nd Earl of Exeter. Through the marriage of the 2nd Earl's daughter, Lady Elizabeth Cecil, the estate passed to Thomas Howard, 1st Earl of Berkshire, and then to their third son, Henry Howard (a playwright). Following Henry's death, the estate passed to his nephew Craven Howard (d.1700; son of Henry's brother Thomas and father of Henry Howard, 11th Earl of Suffolk).

Nothing of the abbey is visible today which was to the SW of the present house and the village of Revesby. Excavations undertaken in 1869 only located the abbey church and cloister. In 1870 the skeletons of several monks were found. Earthworks indicate the extent of the abbey precinct, and reveal the location of 3 rectangular fishponds.
