绊脚石（德语：Stolpersteine），是由德国艺术家冈特·德姆尼希发起的一个艺术项目。所谓“绊脚石”，是棱长10厘米的立方体混凝土块，其中一面贴嵌了一块镌刻着专门纪念文本的黄铜板。有时，以长条形出现的绊脚石也被称作绊脚坎（德语：Stolperschwelle）。这个艺术项目的目的是纪念在德国国家社会主义时期，被纳粹政府谋杀、驱逐和逼迫自杀的人。刻有受难者姓名的绊脚石，就是他们的纪念牌。通常，绊脚石铺设在受难者生前住所门前的路面上，与普通的铺路石平齐。目前，已经有55000块绊脚石被铺设在德国和欧洲的其他国家。

A stolperstein (German pronunciation:[ˈʃtɔlpəʁˌʃtaɪn] from German, literally "stumbling stone") is a type of monument created by artist Gunter Demnig to commemorate victims of Nazi oppression, including the Holocaust. Stolpersteins are small, cobblestone-sized memorials for individual victims of Nazism. They commemorate individuals – both those who died and survivors – who were consigned by the Nazis to prisons, euthanasia facilities, sterilization clinics, concentration camps, and extermination camps, as well as those who responded to persecution by emigrating or committing suicide.
