"The Stockbroker's Clerk" is one of the 56 short Sherlock Holmes stories written by Sir Arthur Conan Doyle. It is the fourth of the twelve collected in The Memoirs of Sherlock Holmes in most British editions of the canon, and third of eleven in most American ones (owing to the omission of the "scandalous" "Adventure of the Cardboard Box"). The story was first published in Strand Magazine in March 1893 and featured seven illustrations by Sidney Paget.

A young clerk, Hall Pycroft, consults Holmes with his suspicions concerning a company that has offered him a very well-paid job. Holmes, Watson and Pycroft travel by train to Birmingham, where the job is initially to be based, and Pycroft explains that he was recently made redundant from a stockbroking house. He eventually secured a new post with another group of stockbrokers, Mawson and Williams, in Lombard Street in the City. Before taking up the job, he was approached by Arthur Pinner, who offered him a managership with a newly established hardware distribution company, to be based in France.
