Else Lieschen Frida "Elsa" Ehrich (8 March 1914 – 26 October 1948) was an SS guard at the Nazi concentration camps, including at Kraków-Płaszów and the Majdanek concentration camp during World War II. She was tried in Lublin, Poland at the Majdanek Trials and sentenced to death for war crimes. Ehrich was hanged on 26 October 1948.
She was an Oberaufseherin at Majdanek, and took active part in all the major selections to the gas chambers and executions. She maltreated prisoners, not sparing even children. Her assistant was reportedly Hermine Braunsteiner, who was later denaturalized and deported from the United States back to Germany.
