This is a list of fictional detective teams from popular detective fiction. This list includes pairs or groups of characters who appear in a series of novels or short stories, not characters who are teamed only for a single story.

Where two detectives work together, they are listed as A and B; where a single detective is regularly accompanied by a non-detecting sidekick or chronicler they are listed as A with B. The author who created the team appears in parentheses.
