Citadel of Raymond de Saint-Gilles, also known as Tripoli Citadel or Qalaat Sanjil, is a historical Crusaders citadel located in Tripoli, North Governorate, Lebanon. It was built in 1103 AD by Raymon De Saint-Gilles (Raymond IV, Count of Toulouse), ruler of Tripoli and one of the leaders of the First Crusade. During the Mamluk era, the castle was burned in 1289 and later restored by the governor of Tripoli, Saif al-Din Asnad Markuji. The castle was also restored by Ottomans during the reign of Sultan Suleiman the Magnificent.
