SS-Oberabschnitt Elbe (SS Senior District Elbe) was a division strength command of the Allgemeine-SS which encompassed the General SS-commands of central east Germany, in today what is near to the border of the Czech Republic. During the Second World War, the Oberabschnitt was considered part of War District IV and was under the authority of an SS and Police Leader of the same name (HSSPF Elbe). Administratively, the Oberabschnitt leader and the SS and Police commander were typically the same person.
The Oberabschnitt collapsed in 1945 as Nazi Germany was invaded. One of the subordinate commands was SS-Abschnitt XXXVII.
