The Adventure of the Dancing Men, a Sherlock Holmes story written by Sir Arthur Conan Doyle, is one of 13 stories in the cycle published as The Return of Sherlock Holmes in 1905. Doyle ranked The Adventure of the Dancing Men third in his list of his twelve favorite Holmes stories. This is one of only two Sherlock Holmes short stories where Holmes' client dies after seeking his help. The other is The Five Orange Pips, part of The Adventures of Sherlock Holmes. The original title was The Dancing Men, when it was published as a short story in The Strand Magazine in December 1903.

The story begins when Hilton Cubitt of Ridling Thorpe Manor in Norfolk visits Sherlock Holmes and gives him a piece of paper with the following mysterious sequence of stick figures. - Cubitt explains to Holmes and Dr. Watson that he has recently married an American woman named Elsie Patrick. Before the wedding, she had asked her husband-to-be never to ask about her past, as she had had some "very disagreeable associations" in her life, although she said that there was nothing that she was personally ashamed of. Their marriage had been a happy one until the messages began to arrive, first mailed from the United States and then appearing in the garden.
