Baldrick is the name of several fictional characters featured in the long-running BBC historic comedy television series Blackadder. Each one serves as Edmund Blackadder's servant and sidekick and acts as a foil and arguably the best friend of the lead character. Each series of Blackadder is set in a different period in British history, and each Baldrick character is a descendant of the Baldrick from the preceding series. Just as Blackadder exists in many incarnations throughout the ages, so does Baldrick; whenever there is a Blackadder there is a Baldrick serving him. They are all portrayed by Sir Tony Robinson.

Blackadder is a series of four period British sitcoms, plus several one-off instalments, which originally aired on BBC1 from 1983 to 1989. All television episodes starred Rowan Atkinson as the antihero Edmund Blackadder and Tony Robinson as Blackadder's dogsbody, Baldrick. Each series was set in a different historical period, with the two protagonists accompanied by different characters, though several reappear in one series or another, e.g., Melchett, Lord Percy Percy / Captain Darling and George.
