Created by Steven Moffat and Mark Gatiss, the show stars Benedict Cumberbatch as Sherlock Holmes and Martin Freeman as Doctor John Watson. Thirteen episodes were produced, with four three-part series airing from 2010 to 2017 and a special episode that aired on 1 January 2016. The series is set in the present day. The one-off special features a Victorian-period fantasy resembling the original Holmes stories.

Sherlock was produced by the BBC, along with Hartswood Films; Moffat, Gatiss, Sue Vertue and Rebecca Eaton were the executive producers. The series was supported by the American station WGBH-TV Boston for its PBS anthology series, Masterpiece, where it also aired in the United States. The series was filmed primarily in Cardiff. North Gower Street in London was used for exterior shots of Holmes's and Watson's 221B Baker Street residence.
