Gainsborough is a town in Lincolnshire, England. The West Lindsey Council headquarters are based in Gainsborough.

The town's main attractions are Gainsborough Old Hall, Gainsborough Castle and West Lindsey Leisure Centre.

Gainsborough Old Hall is a large 15th century timber-framed medieval strong house, it is over 500 years old and is one of the best preserved manor houses in Britain. Sir Thomas Burgh built it between 1460 and 1480. It boast a magnificent Great Hall and strong brick tower. King Richard III in 1483 and King Henry VIII in 1541 both stayed at the Old Hall.

Plans to expand Gainsborough as a new town, linked with Sheffield, never came to fruition, so it remains a small market town. The River Trent runs right along side Gainsborough, and recently the river banks have been renovated to provide residents and tourist with access to the riverside and a sitting area to enjoy the view.
