The Debian System is a 2005 non-fiction book written by Martin Krafft which deals exclusively with Debian GNU/Linux, detailing its internal workings. The book is mostly for the experienced users seeking in-depth technical knowledge, rather than for beginners.

The book was written for publication by Open Source Press and later licenced for co-publication by No Starch Press. The English version is thus released under two different ISBNs:
Due to popular demand, the book was later translated to German, Japanese, and French. A Chinese translation is in the works, and other languages are planned:
The book is dedicated to Aline (Krafft's girlfriend at the time), and the musician Peter Gabriel.
