This is a list of characters in the game of Cluedo (UK) / Clue (US).

Victim The victim of Cluedo/Clue is Dr. Black (UK) / Mr. Boddy (US), the wealthy owner of Tudor Mansion (formerly known as Tudor Close/Tudor Hall (UK) and Boddy Mansion/Boddy Manor (US)). He is the unseen host who is murdered, which inspires the quest to discover who murdered him, what room in his mansion the crime occurred, and with what weapon. Dr. Black was listed in the original patent filing as one of the ten characters created for the game, in which one character was drawn from the suspect cards to be the new victim before the start of a game. Mr. Boddy's name is a pun on the fact that the character is a dead body.

In the 2002 US edition, Mr. John Boddy was orphaned at a young age and raised by his uncle, Sir Hugh Black, and is also known by locals as Dr. Black. He is an eminent anthropologist and the heir of the late Sir Hugh's estate, which he is set to fully inherit on the day of his thirtieth birthday. Before then, Boddy discovered a series of secret allowances bequeathed to some of his uncle's former associates. Vowing to investigate these financial dealings, he invites his uncle's associates to Tudor Mansion for a weekend visit. However, Mr. Boddy is murdered by one of them.

In the 2023 edition of the game, the two names are combined into the character Boden "Boddy" Black Jr, a man who inherited his significant wealth. At the time of his murder in the game's updated story, he has used connections to government officials in Hue County, the game's setting, to push through permitting and construction on Boden Black Hotel, a luxury hotel that the public opposes.

In the 1985 film, Mr. Boddy is portrayed by Lee Ving and depicted as blackmailing the six suspects using his network of informants.
