克诺索斯（希腊语：Κνωσός）是克里特岛上的一座米诺斯文明遗迹，被认为是传说中米诺斯王的王宫。它位于克里特岛的北面，海岸线的中点，是米诺斯时代最为宏伟壮观的遗址，可能是整个文明的政治和文化中心。克诺索斯遗址是由英国考古学家阿瑟·伊文思于1878年进行了最早的完整发掘，发现了大批米诺斯遗迹，和许多刻有使用线形文本A的文本的泥板，揭示了米诺斯文明的存在。其中最为辉煌的米诺斯王宫始建于约前2100年至前1800年，后几经扩建，占地约一万三千平方公尺，围绕着一个1200平方公尺的中心院落展开成四个翼，上下五层楼，共有一千多间房间。

The name Knossos survives from ancient Greek references to the major city of Crete. The identification of Knossos with the Bronze Age site is supported by tradition and by the Roman coins that were scattered over the fields surrounding the pre-excavation site, then a large mound named Kephala Hill, elevation 85 m (279 ft) from current sea level. Many of them were inscribed with Knosion or Knos on the obverse and an image of a Minotaur or Labyrinth on the reverse, both symbols deriving from the myth of King Minos, supposed to have reigned from Knossos. The coins came from the Roman settlement of Colonia Julia Nobilis Cnossus, a Roman colony placed just to the north of, and politically including, Kephala. The Romans believed they had colonized Knossos. After excavation, the discovery of the Linear B tablets, and the decipherment of Linear B by Michael Ventris, the identification was confirmed by the reference to an administrative center,
