This is a list of characters that appear in the British murder mystery series Midsomer Murders.

Detective Chief Inspector Thomas "Tom" Geoffrey Barnaby (John Nettles) (series 1-13)—A senior member of Causton CID, Barnaby used to work for MI6. A patient, tolerant man, Barnaby's style of investigation is methodical and fair. Barnaby is a sagacious and perceptive individual, able to recognise seemingly obscure clues. Barnaby's social life revolves around his wife Joyce and his daughter Cully, who often provide a personal connection with the crimes that he is investigating. Barnaby's parents are both deceased by the episode "Blue Herrings". In his last appearance, "Fit for Murder", we learn that his father died on his birthday, at Barnaby's current age.

Detective Chief Inspector John Barnaby (Neil Dudgeon) (series 13, series 14-present)—Barnaby transferred from Brighton to Midsomer's Causton CID to replace his older cousin, Chief Inspector Tom Barnaby, when Barnaby retired. He has a degree in Psychology from Durham University, which earned him some ribbing from DS Jones when he first arrived; however, despite a rocky start, the two make a formidable team. Barnaby lives in a large country cottage with his wife Sarah, daughter Betty, and their dog Sykes (later Paddy). He first makes a guest appearance in the series 13 episode, "The Sword of Guillaume" before taking over in the series 14 premiere, "Death in the Slow Lane." Dudgeon actually made his first appearance on the show not as John Barnaby, but as womanising gardener Daniel Bolt in the series 4 opener "Garden of Death".

Joyce Barnaby (Jane Wymark) (series 1-13)—DCI Tom Barnaby's long-suffering wife. She is tolerant of her husband, despite his being a workaholic who spent their honeymoon solving the case of the "Pimlico Poisoner", which suggests that they met in London. Joyce is an easy-going and friendly woman who likes to be involved in community activities. She has long possessed a desire to move out of their Causton home and into one of the picturesque Midsomer villages—only to be put off by the grisly murders that occur there. She's known to her family as an experimental, but not always successful, cook. Thus, Tom is often seen taking advantage of every opportunity to dine out. She married Tom in 1973 and their only child, Cully, was born five years later in 1978. Her parents are called Muriel and Douglas.
