Inside the Third Reich (German: Erinnerungen, "Memories") is a memoir written by Albert Speer, the Nazi Minister of Armaments from 1942 to 1945, serving as Adolf Hitler's main architect before this period.

Speer joined the National Socialist Party in January 1931; he wrote "I was not choosing the NSDAP, but becoming a follower of Hitler, whose magnetic force had reached out to me the first time I saw him and had not, thereafter, released me."

Speer described the personalities of many Nazi officials, including Joseph Goebbels, Hermann Göring, Heinrich Himmler, Rudolf Hess, Martin Bormann, and, of course, Hitler himself.

The main body of the book effectively ends when Speer, by this point having joined Karl Dönitz's government seated in Schleswig-Holstein, receives news of Hitler's death.

It takes the reader inside Nazi Germany on four different levels: Hitler's inner circle, National Socialism as a whole, the area of wartime production and the inner struggle of Albert Speer.
