"A Scandal in Bohemia" is the first short story, and the third overall work, featuring Arthur Conan Doyle's fictional detective Sherlock Holmes. It is the first of the 56 Holmes short stories written by Doyle and the first of 38 Sherlock Holmes works illustrated by Sidney Paget. The story is notable for introducing the character of Irene Adler, who is one of the most notable female characters in the Sherlock Holmes series, despite appearing in only one story. Doyle ranked "A Scandal in Bohemia" fifth in his list of his twelve favourite Holmes stories.

Traditionally, the canon of Sherlock Holmes consists of the 56 short stories and four novels written by Sir Arthur Conan Doyle. In this context, the term "canon" is an attempt to distinguish between Doyle's original works and subsequent works by other authors using the same characters. Usually capitalized by aficionados of the Sherlockian game as "the Canon", the description of these 60 adventures as the Sherlock Holmes canon and the game of applying the methods of "Higher Criticism" to it was started by Ronald Knox as a playful use of the traditional definition of canon as an authoritative list of books accepted as holy scripture.
