The siege of Amiens was a siege and battle fought during the Franco-Spanish War (1595–1598), as part of both the French Wars of Religion and the Anglo-Spanish War (1585–1604), between 13 May and 25 September 1597. The Spanish, who had sent a large army in March, had captured the city of Amiens easily in a ruse. Henry IV of France, after the surprise of the capture, immediately and quickly built up an army which included a large English force and besieged Amiens on 13 May.

The Anglo-Spanish War (1585–1604) was an intermittent conflict between the Habsburg Kingdom of Spain and the Kingdom of England that was never formally declared. It began with England's military expedition in 1585 to what was then the Spanish Netherlands under the command of the Earl of Leicester, in support of the Dutch rebellion against Spanish Habsburg rule.
