The Raid on Boulogne in 1804 was a naval assault by elements of the Royal Navy on the fortified French port of Boulogne-sur-Mer, during the Napoleonic Wars.

Despite its ambitious aims the assault produced little material damage to the French fleet anchored in the harbour, but did perhaps contribute to a growing sense of defeatism amongst the French as to their chances of crossing the English Channel in the face of the Royal Navy and launching a successful invasion of the United Kingdom.
