Encyclopedia of Camps and Ghettos, 1933–1945 is a seven-part encyclopedia series that explores the history of the concentration camps, ghettos, forced-labor camps, and other sites of detention, persecution, or state-sponsored murder run by Nazi Germany and other Axis powers in Europe and Africa. The series is produced by the United States Holocaust Memorial Museum (USHMM) and published by Indiana University Press. Research began in 2000; the first volume was published in 2009; and the final volume is slated for publication in 2025. Along with entries on individual sites, the encyclopedias also contain scholarly overviews for historical context.

From 1933 to 1945, Nazi Germany operated more than a thousand concentration camps, including subcamps on its own territory and in parts of German-occupied Europe.
