The Bayeux Tapestry is an embroidered cloth nearly 70 metres (230 ft) long and 50 centimetres (20 in) tall, which depicts the events leading up to the Norman conquest of England concerning William, Duke of Normandy, and Harold, Earl of Wessex, later King of England, and culminating in the Battle of Hastings. It is thought to date to the 11th century, within a few years after the battle. It tells the story from the point of view of the conquering Normans, but is now agreed to have been made in England.

The cloth consists of some seventy scenes, many with Latin tituli, embroidered on linen with coloured woollen yarns. It is likely that it was commissioned by Bishop Odo, William's half-brother, and made in England—not Bayeux—in the 1070s. In 1729 the hanging was rediscovered by scholars at a time when it was being displayed annually in Bayeux Cathedral. 

The designs on the Bayeux Tapestry are embroidered rather than woven, so that it is not technically a tapestry. Nevertheless, it has always been referred to as a tapestry until recent years when the name "Bayeux Embroidery" has gained ground among certain art historians. It can be seen as a rare example of secular Romanesque art. Tapestries adorned both churches and wealthy houses in Medieval Western Europe, though at 0.5 by 68.38 metres (1.6 by 224.3 ft, and apparently incomplete) the Bayeux Tapestry is exceptionally large. Only the figures and decoration are embroidered, on a background left plain, which shows the subject very clearly and was necessary to cover large areas.
