克拉伦斯·苏厄德·丹诺（英语：Clarence Seward Darrow）（1857年4月18日－1938年3月13日），美国律师。曾为李奥波德与勒伯案、斯科普斯案(The State of Tennessee v. John Thomas Scopes，即有名的进化论法庭辩论)、干草市场暴乱(发生于1886年的工人抗议引发的暴乱事件，之后成为国际劳动节的起源)等大案作辩护律师而闻名。丹诺一生义务为无助的弱势团体与穷人辩护，他的名言是：「一个人在未定罪前，都是无辜的。」、「我恨罪行，但从不恨罪人」丹诺反对死刑，他在《丹诺自传》中曾指出：犯罪是社会本身有问题，才会造成犯罪问题，今天解决犯罪者并无法解决问题的根本。丹诺为了争取公民权利而辩护、批判不合时宜的司法体制，使得他被认为是美国最伟大的民权律师。

Clarence Seward Darrow (/ˈdæroʊ/; April 18, 1857 – March 13, 1938) was an American lawyer, leading member of the American Civil Liberties Union, and prominent advocate for Georgist economic reform. He was best known for defending teenage thrill killers Leopold and Loeb in their trial for murdering 14-year-old Robert "Bobby" Franks (1924). Some of his other notable cases included defending Ossian Sweet, and John T. Scopes in the Scopes "Monkey" Trial (1925), in which he opposed William Jennings Bryan (statesman, noted orator, and three-time presidential candidate). Called a "sophisticated country lawyer", he remains notable for his wit, which marked him as one of the most famous American lawyers and civil libertarians.
