斯图亚特王朝(英语: The House of Stuart/ 盖尔语: Siol Na Stiubhartaich)，初名为斯图尔特王朝(House of Stewart)是1371年至1714年间统治苏格兰和1603年至1714年间统治英格兰和爱尔兰的王朝。

其王室成员的祖先可以追溯至公元11世纪法国布列塔尼的地方贵族。斯图亚特是第一个成功统治整个不列颠群岛的王室。但统治权实际上不太稳定，经历数次革命，两位君主被革命所推翻。同时由于斯图亚特王室的罗马天主教背景，导致基督新教徒为主的英格兰民众经常质疑君主的宗教倾向，令不列颠群岛的不稳定因素增加不少。不过，这些因素促使英国议会权力愈来愈大，使英国最早成为议会制国家，也使英国的民主步伐领先于欧陆诸国。

The House of Stuart is a European royal house. Founded by Robert II, the House of Stuart—also spelled Stewart in Scottish contexts—first became monarchs of the Kingdom of Scotland during the late 14th century before inheriting the kingdoms of England (including Wales) and Ireland in the 17th century. The dynasty's patrilineal Breton ancestors had held the office of High Steward of Scotland since the 12th century, after arriving by way of Norman England. In 1707, Queen Anne became the first monarch of the newly merged Kingdom of Great Britain. The family also maintained the traditional English claims to the Kingdom of France.
