Gainsborough was one of the capital cities of Mercia during the Anglo-Saxon period, which had preceded Danish rule. It is understandable that the Viking kings would have been drawn to it as an administrative centre, being close to the Danish stronghold at Torksey.

In 868 King Alfred married Ealswitha, daughter of Aethelred Mucill, chief of the Gaini, whence the town gets its name.

Historically, Gainsborough is the "capital that never was". Towards the end of July 1013, the Dane Sweyn Forkbeard, together with his son Canute, arrived in Gainsborough with an army of conquest. Sweyn defeated the Anglo-Saxon opposition and King Ethelred fled the country. Sweyn was declared King of England, and he returned to Gainsborough. Sweyn and Canute took up high office at the Gainsborough Castle (on the site of the present-day Old Hall), while his army occupied the camp at Thonock (today known as Castle Hills). But King Sweyn was killed five weeks later when he was thrown from his horse in Gainsborough. His son Canute established a base elsewhere.

King Canute may have performed his unsuccessful attempt to turn the tide back in the River Trent at Gainsborough. Historians believe he may have been demonstrating on the aegir, a tidal bore. He and his supporters may have known Gainsborough was the furthest reach of the aegir, and ideal for his demonstration. However the story was only written down a century later by Henry of Huntingdon, who gives no location, and may have been a myth or a fable.

The Domesday Book (1087) records that Gainsborough was exclusively a community of farmers, villeins and sokemen, tenants of Geoffrey de Guerche. The population was only about 80 people, of which about 70% were of Scandinavian descent.

The Lindsey Survey of 1115-18 records that Gainsborough was then held by Nele d'Aubigny (known as Nigel the Black). He was the forebear of the Mowbray family, and the Mowbray interest in Gainsborough continued until at least the end of the 14th Century.

A weekly market was granted by King John in 1204.

Many scholars believe Gainsborough to be the basis for the fictional town of St Ogg's in George Eliot's The Mill on the Floss (1860). The novelist visited Gainsborough in 1859, staying in the house of a shipbuilder on Bridge Street (which survives today as the United Services Club). The stone bridge and the nearby willow tree are mentioned, and the Old Hall is described in detail. Thomas Miller's Our Old Town published two years before, included the true story of a miller who loses a lawsuit after assaulting his adversary, and George Eliot used a similar story plot in The Mill on the Floss as the basis of the Tuliver/Wakem feud. It's also possible that she witnessed the aegir on the Trent, which inspired the flood in her story's climax.
