提贝里乌斯·克劳狄乌斯·凯撒·奥古斯都·日耳曼尼库斯（拉丁语：Tiberius Claudius Caesar Augustus Germanicus，简称克劳狄乌斯、克劳狄、革老丢、或模仿后来欧洲君**惯冠以数字的克劳狄一世，前10年8月1日－54年10月13日），他是罗马帝国朱里亚·克劳狄王朝的第四任皇帝，41年—54年在位。

克劳狄乌斯是意外而登基为元首的。41年，皇帝卡利古拉遭到刺杀后，近卫军拥立这位克劳狄乌斯家族的中年男子，并受到元老院的承认而继位为罗马皇帝。他的统治力求各阶层的和谐，凡事采取中庸之道，修补了卡利古拉时期皇帝与元老议员之间的破裂关系，提高行省公民在罗马的政治权力，并兴建国家的实业。后期史学家认为，罗马帝国初期政治的中央集权统治型式，是在他的手中和平地转移完成的。

Claudius (/ˈklɔːdiəs/; Latin:Tiberius Claudius Caesar Augustus Germanicus; 1 August 10 BC – 13 October 54 AD) was Roman emperor from 41 to 54. A member of the Julio-Claudian dynasty, he was the son of Drusus and Antonia Minor. He was born at Lugdunum in Gaul, the first Roman Emperor to be born outside Italy. Because he was afflicted with a limp and slight deafness due to sickness at a young age, his family ostracized him and excluded him from public office until his consulship, shared with his nephew Caligula in 37.
