Henry Gray's Anatomy of the Human Body (or Gray's Anatomy as it has commonly been shortened) is an English-language human anatomy textbook widely regarded as a classic work on the subject.

The book was first published under the title Gray's Anatomy: Descriptive and Surgical in the United Kingdom in 1858, and the following year in the United States. While studying the anatomical effects of infectious diseases, Gray contracted smallpox from his dying nephew and died shortly after the publication of the 1860 second edition, at the age of 34. Work on his much-praised book was continued by others and on November 24, 2004, the 39th British edition was released.
