圆桌骑士（英语：Knights of the Round Table），或译成圆桌武士，是中世纪传说中亚瑟王的朝廷中最高等的那些骑士。

温切斯特圆桌历史可及1270年代，列出了25个骑士的名字。每年，亚瑟将骑士们聚集到Pentecost的卡美洛城堡。不同的故事有不同数量的骑士，从12到150、以至1600人不等。与有主次和对立关系的长条桌不同，圆桌代表与会者具有平等的权利。最早描述圆桌的作者是维斯（Wace），他的不列颠传说（Roman de Brutus of Britain Brut）是Geoffrey of Monmouth的不列颠王记（Historia Regum Britanniae）的细化，但即使是最早的作者们，包括Geoffrey和威尔斯亚瑟传说（参见Mabinogion）将下列出众的战士归于亚瑟的领导。

The Round Table is King Arthur's famed table in the Arthurian legend, around which he and his Knights congregate. As its name suggests, it has no head, implying that everyone who sits there has equal status. The table was first described in 1155 by Wace, who relied on previous depictions of Arthur's fabulous retinue. The symbolism of the Round Table developed over time; by the close of the 12th century it had come to represent the chivalric order associated with Arthur's court, the Knights of the Round Table.
