Otto Erbersdobler (30 April 1895 – 25 October 1981) was a Nazi Party (NSDAP) official who served as the Gauleiter of Lower Bavaria from 1929 to 1932.

From May 1915 to December 1918, Erbersdobler took part in World War I as a member of the Bavarian 15th Infantry Regiment.

He then served as an Ortsgruppenleiter (Local Group Leader) in his hometown for the Völkisch-Social Bloc, a Nazi front organization active during the ban.

On 1 March 1929, Erbersdobler succeeded Gregor Strasser as Gauleiter for the Gau of Lower Bavaria.

When the two jurisdictions formally merged into Gau Lower Bavaria-Upper Palatinate on 17 August 1932, Erbersdobler served as Deputy Gauleiter under Maierhofer until 19 January 1933.

In December 1935, Erbersdobler switched from the SA to the National Socialist Motor Corps (NSKK), where he served as the Liaison Leader for Ideological Indoctrination in the Motorbrigade of Gau Bavarian Eastern March.
