Trakai Island Castle (Lithuanian: Trakų salos pilis) is an island castle located in Trakai, Lithuania on an island in Lake Galvė. The construction of the stone castle was begun in the 14th century by Kęstutis, and around 1409 major works were completed by his son Vytautas the Great, who died in this castle in 1430. Trakai was one of the main centres of the Grand Duchy of Lithuania and the castle held great strategic importance.

Trakai Island Castle was built in several phases. During the first phase, in the second half of the 14th century, the castle was constructed on the largest of three lake islands by the order of Grand Duke Kęstutis. The construction of Trakai Island Castle was related to the expansion and strengthening of the Trakai Peninsula Castle. Kęstutis moved his main residence and his treasury to the Island Castle.

The castle suffered major devastation during an attack by the Teutonic Knights in 1377. After the assassination of Kęstutis, a power struggle between Jogaila and Vytautas the Great for the title of Grand Duke of Lithuania began. The castle was besieged by both sides. Soon after the reconciliation between Jogaila and Vytautas, the second phase of construction started and continued until 1409. This phase is regarded as the major development in the history of the castle. Apparently, during the truce with the Teutonic Order, the construction works were supervised by the Order's stonemason Radike, four years before the Battle of Grunwald.

During the second phase, two wings were added, and on the southern side a 6-storey (35-metre or 115-foot high) donjon was built. The donjon had movable gates which separated the palace from the forecastle. The donjon was used for several functions; besides serving as another defensive structure, it had a chapel and living quarters. It was linked to the multi-storey Ducal Palace, which had an inner yard. The inner yard had wooden galleries, which ran around the inner wall; these galleries were used to access various support facilities without going inside the palace itself.
