Johnlock
Johnlock (short for John/Sherlock) is the fan nickname for the hypothetical romantic relationship ("ship") between the character Sherlock Holmes and his companion John Watson as depicted in the BBC series Sherlock (2010–2017). Fan artwork and slash fiction of the two as a romantic or sexual pairing became popular on Tumblr particularly among young queer women, and Sherlock Holmes/John Watson remains a common pairing on the fan fiction site Archive of Our Own.
Some fans and academics have accused the show of queerbaiting—subtextually hinting at the possibility of romance between its two male leads, to attract an LGBTQ audience. In interviews, John's actor Martin Freeman, and showrunners Mark Gatiss and Steven Moffat denied that this was their intention, saying the show's "gay references", such as Sherlock and John being repeatedly mistaken for a couple, were meant as jokes.
A fan theory called The Johnlock Conspiracy (TJLC) speculated that showrunners had intended a romantic reading, and planted various clues that the ship would eventually become canon within the show, though this never materialized.
