Bergenhus fortress (Norwegian: Bergenhus festning) is a fortress located in Bergen, Norway. Bergenhus fortress is located in the entrance to the harbour in Bergen. It is one of the oldest and best preserved castles in Norway.

The fortress contains buildings dating as far back as the 1240s, as well as later constructions built as recently as World War II. The extent of the enclosed area of today dates from the early 19th century. In medieval times, the area of the present-day Bergenhus Fortress was known as Holmen (The islet) and contained the royal residence in Bergen, as well as a cathedral, several churches, the bishop's residence, and a Dominican monastery. Excavations have revealed foundations of buildings believed to date back to before 1100, which might have been erected by King Olav Kyrre. In the 13th century, until 1299, Bergen was the capital of Norway and Holmen was thus the main seat of Norway's rulers. It was first enclosed by stone walls in the 1240s.

Of the medieval buildings, a medieval hall and a defensive tower remain. The royal hall, today known as Haakon's Hall, built around 1260, is the largest medieval secular building in Norway. The defensive tower, known in the Middle Ages as the keep by the sea, was built around 1270 by King Magnus VI Lagabøte, and contained a royal apartment on the top floor. In the 1560s it was incorporated by the commander of the castle, Erik Rosenkrantz, into a larger structure, which is today known as the Rosenkrantz Tower.

In the Middle Ages, several churches, including Christ Church, Bergen's cathedral, were situated on the premises. These, however, were torn down between 1526 and 1531, as the area of Holmen was converted into a purely military fortification under Danish rule. From around this time, the name Bergenhus came into use. Building work on Christ Church probably started around 1100. It contained the shrine of Saint Sunniva, the patron saint of Bergen and western Norway. In the 12th and 13th centuries it was the site of several royal coronations and weddings. It was also the burial site of at least six kings, as well as other members of the royal family. The site of its altar is today marked by a memorial stone.
