The Monument to the Great Fire of London, more commonly known simply as the Monument, is a fluted Doric column in London, England, situated near the northern end of London Bridge. Commemorating the Great Fire of London, it stands at the junction of Monument Street and Fish Street Hill, 202 feet (62 m) in height and 202 feet west of the spot in Pudding Lane where the Great Fire started on 2 September 1666. Constructed between 1671 and 1677, it was built on the site of St Margaret, New Fish Street, the first church to be destroyed by the Great Fire. It is Grade I-listed and is a scheduled monument. Another monument, the Golden Boy of Pye Corner, marks the point near Smithfield where the fire was stopped.

The Great Fire of London was a major conflagration that swept through central London from Sunday 2 September to Thursday 6 September 1666, gutting the medieval City of London inside the old Roman city wall, while also extending past the wall to the west. The death toll is generally thought to have been relatively small, although some historians have challenged this belief.
