Blankenberge is a seaside municipality and city located in the Belgian province of West Flanders. Situated on the North Sea coast, it serves as an important administrative unit within the region. The municipality comprises the town of Blankenberge proper along with the settlement of Uitkerke. Its geographical position places it directly on the Belgian coastline, defining its identity as a coastal hub.

Fishing activities in the area date back to the 11th century, with a fleet exceeding sixty ships by the 12th century. A pontoon was constructed in the 15th century near the lighthouse, and a navigation channel with a wharf arrived in 1871. The fishery declined between the world wars and disappeared in 1945 after the port was destroyed during World War II. A new pleasure boat port was rebuilt in 1955.

Tourism began developing in the first half of the 18th century, with bathing becoming popular in the 19th century influenced by English visitors. The town features a long sandy beach and the Belgium Pier, a 350-metre Art Deco structure built in 1933. During the Belle Époque, it was a favorite destination for royalty and the wealthy, including Archduke Franz Ferdinand, who stayed at the Grand Hotel des Bains et des Families.

The city hosts various cultural events, including the Flower Parade on the last Sunday of August and the annual Carnival Parade. It has been a filming location for movies such as Franz and Le Tout Nouveau Testament. Historically, it attracted international artists like Enrico Caruso and hosted events like Spécial les vacances in 1979. The World's Largest Sand Sculpture Festival took place on the beach until 2012.

The population was recorded at 20,349 as of 2018. Transport access is facilitated by Blankenberge railway station, opened in 1863, with trains to Brussels and the Kusttram running along the coast. The economy relies heavily on tourism, with infrastructure expanding to accommodate summer visitors. The area includes nature reserves like Zeebos and De Fonteintjes to the east.
