A Guide for the Perplexed is a short book by E. F. Schumacher, published in 1977. The title is a reference to Maimonides's The Guide for the Perplexed. Schumacher himself considered A Guide for the Perplexed to be his most important achievement, although he was better known for his 1973 environmental economics bestseller Small Is Beautiful, which made him a leading figure within the ecology movement. His daughter wrote that her father handed her the book on his deathbed, five days before he died and he told her "this is what my life has been leading to". As the Chicago Tribune wrote, "A Guide for the Perplexed is really a statement of the philosophical underpinnings that inform Small Is Beautiful".

Schumacher describes his book as being concerned with how humans live in the world. It is also a treatise on the nature and organisation of knowledge and is something of an attack on what Schumacher calls "materialistic scientism". Schumacher argues that the current philosophical "maps" that dominate western thought and science are both overly narrow and based on some false premises. However, this book is only in small part a critique.
