The Iron Heel is a dystopian novel by American writer Jack London, first published in 1908. Generally considered to be "the earliest of the modern Dystopian," it chronicles the rise of an oligarchic tyranny in the United States. It is arguably the novel in which Jack London's socialist views are most explicitly on display. A forerunner of soft science fiction novels and stories of the 1960s and 1970s, the book stresses future changes in society and politics while paying much less attention to technological changes. The book is uncommon among London's writings (and in the literature of the time in general) in being a first-person narrative of a woman protagonist written by a man.

美国作家杰克·伦敦的长篇小说《铁蹄》幻想了一个距今七百年后的"大同世界"，当时的一位考古学者发现了《埃弗哈德手稿》，也就是本书。手稿作者阿维丝·埃弗哈德是美国社会党领袖欧内斯特·埃弗哈德的妻子。小说用细腻的笔触，从一个女性的视角，讲述了二十世纪初劳动人民对抗财阀阶级的惨烈而激动人心的斗争，塑造了欧内斯特这位革命领袖的光辉形象，同时揭露了美国民主的真相，并预言了财阀阶级的寡头政权（即"铁蹄"）走向法西斯统治的必然。
