The Port of Boulogne-sur-Mer is a seaport located on the western coast of the Hauts-de-France region, on the edge of the Pas de Calais, the world's busiest strait for international shipping. It is France's leading fishing port, with a diversified fleet of almost 150 boats. It was also an important link port with England until the end of the 20th century. It became a “regional port” in 2007 as part of port decentralization.

Boulogne-Maritime was a former railway station and port in Boulogne-sur-Mer, France. Ferries between England and France used the terminal. The Station was the second most important passenger port of France (after Marseille), seeing 563,000 passengers use the facility in 1938. Following World War II, traffic with England was restored in 1947. In June 1952 a new ferry terminal was opened, located on the site of the previous one established in 1875. The modern redesign of the terminal allowed boarding of cars onto the boats heading for England. The station saw intense activity even in the 1990s. As of 2012, the site "is at the heart of a vast urban redefinition project". Since the station closed, it has been used for various cultural functions, such as a mobile museum (the Centre Pompidou mobile) from June to September 2012.

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. It differed from the conventional tactics of naval assaults of the period by utilizing a wide range of new equipment produced by the American inventor Robert Fulton, with the backing of the Admiralty. 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.

The First Siege of Boulogne took place from 19 July to 14 September 1544 and the Second Siege of Boulogne took place in October 1544. An earlier Siege of Boulogne had taken place in 1492 when the English Tudor King Henry VII laid siege to the lightly defended lower town of Boulogne in the Pas-de-Calais, France. Fifty years later as allies of the Holy Roman Emperor Charles V, during the war against the French, the English returned led by Henry VII's son and heir, Henry VIII. Boulogne was fortified and defended as an English possession on the French mainland between 14 September 1544 and March 1550.

Boulogne-sur-Mer (French: [bulɔɲ syʁ mɛʁ] ; Picard: Boulonne-su-Mér; Dutch: Bonen; Latin: Gesoriacum or Bononia), often called just Boulogne (UK: , US: ), is a coastal city in Northern France. It is a sub-prefecture of the department of Pas-de-Calais. Boulogne lies on the Côte d'Opale, a touristic stretch of French coast on the English Channel between Calais and Normandy, and the most visited location in the region after the Lille conurbation. Boulogne is its department's second-largest city after Calais, and the 183rd-largest in France. It is also the country's largest fishing port, specialising in herring. Boulogne is an ancient town and was the main Roman port for trade and communication with its Province of Britain. After a period of Germanic presence following the collapse of the Empire, Boulogne was integrated into the County of Boulogne of the Kingdom of France during the Middle Ages. It was occupied by the Kingdom of England numerous times due to conflict between the two nations. In 1805 it was a staging area for Napoleon's troops for several months during his planned invasion of the United Kingdom. The city's 12th-century belfry is recognised by UNESCO as a World Heritage Site (along with other belfries of Belgium and France), while another popular attraction is the marine conservation centre Nausicaa.
