The Schaffhausen massacre was an anti-Semitic episode in Schaffhausen, in present-day Switzerland, which occurred in 1401. An episode of antisemitism had already occurred in Schaffhausen 52 years prior, when the local Jews were accused of well poisoning and burned alive on 22 February 1349. On this occasion, the Jews were accused of the murder of a four-year-old boy, Konrad Lori from Diessenhofen. Forced confession were obtained from them, and on 25 June 1401 they were executed by burning.
Today, there is a plaque in Schaffhausen, commemorating the suffering of the Schaffhausen Jews in the Middle Ages.
