The Cosmic Landscape is a non-fiction popular science book on the anthropic principle and string theory landscape. It is written by theoretical physicist Leonard Susskind. The book was initially published by Little, Brown and Company on December 12, 2005.

Susskind writes in the preface that the book is mainly about "the scientific explanations of the apparent miracles of physics and cosmology and its philosophical implications". The book deals with the Anthropic principle. The earlier chapters deal with topics such as quantum electrodynamics, Feynman diagrams and quantum chromodynamics. Later on, the cosmological constant is introduced and problems with the amount of energy produced from virtual particles. String theory is also introduced and the black hole war.

The book emphasizes the theory of a "landscape" with many universes out there. Instead of the fact that the Universe is somehow just perfect for life, the truth is that "it's not that the universe is somehow contorting itself to accommodate us; it's just a diverse place and we find ourselves in a friendly corner".
