刻耳柏洛斯（古希腊语：Κέρβερος，Kerberos，[ˈkerberos]，英语：Cerberus，英语发音：/ˈsɜrbərəs/），也称基路比罗斯、塞尔伯洛斯或赛伯拉斯（希腊语：Κέρβερος，字面意思为“黑暗中的恶魔”），希腊神话中看守冥界入口的恶犬。赫西俄德在《神谱》中说此犬有50个头，而后来的一些艺术作品则大多表现它有3个头（可能是为了便于雕刻所致）；因此在汉语语境里（尤其是通俗文化中）也常称这怪物为地狱三头犬。

In Greek mythology, Cerberus (/ˈsɜːrbərəs/; Greek: Κέρβερος Kerberos [ˈkerberos]), often called the "hound of Hades", is a monstrous multi-headed dog, who guards the gates of the underworld, preventing the dead from leaving. He was the offspring of the monsters Echidna and Typhon, and is usually described as having three heads, a serpent for a tail, with snakes protruding from various parts of his body. Cerberus is primarily known for his capture by Heracles, one of Heracles' twelve labours.
