Inside the Third Reich is a famous book of memoirs written by Albert Speer. From 1946 to 1966, while serving the prison sentence handed down from the Nuremberg War Crimes tribunal, Albert Speer penned 1,200 manuscript pages of personal memoirs.

Titled Erinnerungen ("Recollections") upon their 1969 publication in German, Speer's critically acclaimed personal history was translated into English and published one year later as Inside the Third Reich.
