Syon Abbey, (or Sion Abbey) was a major medieval monastery of the Bridgettine Order, its major site bordering Brentford and Isleworth, Middlesex, England.

A double monastery of men and women, under an abbess, Syon Abbey was founded in 1414 or 1415 at Twickenham Park, London by King Henry V of England. It was built in his 'manor of Isleworth Syon', located on the Middlesex bank of the River Thames opposite the royal palace in Richmond, on the boundary of the parish of Twickenham, near where Twickenham bridge crosses the river today. Under royal patronage, the Abbey grew quickly, relocating in 1431 and soon extending half a mile along the north bank of the Thames, near Brentford, using buildings constructed for a Celestine order, but never occupied, sited at the present day residence of the Duke of Northumberland, Syon House. The chief duty of the community was to pray for the souls of the royal founder and for all the faithful departed. However the abbey also became a centre of preaching and scholarship with one of the major libraries of England.

The Abbess governed the Order; while a Confessor-General, elected by the brothers, controlled the spiritual direction. The Sisters had their own convent on one side of the shared, double-aisled church, with the accommodation for the Brothers on the other side.

During the Reformation St Richard Reynolds and other brothers were hung, drawn and quartered for their opposition to King Henry VIII. The abbey was destroyed by the King in 1539 during the dissolution of the monasteries, and the community expelled. A long-standing legend states that King Henry VIII´s coffin, lying in the ruined chapel at Syon on its way to Windsor for burial, burst open during the night and in the morning dogs were found licking up the remains. This was regarded as divine judgement for his desecration of the abbey.

The community was re-established at Syon in 1557, under Queen Mary I, but were driven into exile again under Elizabeth I. The expelled community moved from place to place in France and Spain, until they finally settled in Lisbon, Portugal, in 1594. The Lisbon community returned to England in 1861, settling first in Spettisbury , Dorset, in 1887 in Chudleigh , Devon and then in 1925 to its current location near to South Brent , Devon. As such, the Abbey of Syon has the distinction of being the only English monastic community that survived the reformation in an unbroken lineage to the present day.

In 2004, the remaining mediaeval books in the Abbey's collection were deposited for safe-keeping with the University of Exeter Library.
