David Brent is a fictional character in the BBC television mockumentary The Office, portrayed by the show's co-creator, co-writer, and co-director Ricky Gervais. Brent is a white-collar office middle-manager and the principal character of the series. He is the general manager of the Slough branch of Wernham Hogg paper merchants and the boss of most other characters in the series. Much of the comedy of the series centres on Brent's many idiosyncrasies, hypocrisies, self-delusions, and overt self-promotion.

Gervais came up with the basic idea of Brent several years before The Office's debut in 2001. "David Brent was like a Frankenstein of all the people I'd met in my adult life. He was just a guy who wanted to be loved." Gervais based the filming format on reality-television series such as Airport. He had also worked in an office environment for almost ten years.

Brent is presented as an employer who wholeheartedly believes that his staff love him, whereas in fact, apart from Gareth Keenan, they actually resent him. In the Series 1 finale Brent betrays his staff by accepting a promotion to higher management, saving himself from the downsizing that will befall the Slough branch. Brent is later forced to turn the position down after failing a medical examination, but he insists to his staff that he failed it on purpose to save the branch.

Despite being the manager, Brent avoids confrontation. Brent's inability to stand up for himself or his staff often results in him lashing out at them, pointing out their weight or age if his own is brought to ridicule.

In the second series, Neil Godwin, manager of the Swindon branch, is given Brent's promotion. Neil is shown to be everything that Brent is not, which provokes Brent's insecurity and jealousy. Neil effortlessly bonds with Brent's staff and earns their trust, essentially going over Brent's head. Brent's dismissive attitude to key issues such as this culminates in a later confrontation with Neil and Jennifer when Brent fails to produce a report he promised to do. When given an official warning, Brent recklessly challenges Neil in an effort motivated by his hurt pride, stating that his removal from managing the Slough branch would result in a staff uprising. This proves to be baseless and his staff are shown to be completely unconcerned and even relieved by the announcement that Brent will be made redundant.

Despite his unlikeable nature, Brent is shown as an increasingly tragic figure: a lonely man without any friends, goals or achievements who would rather please everybody around him even if it is met at his own expense.

In the Christmas special, Brent is working as a travelling salesman following his dismissal from Wernham Hogg, but he remains emotionally attached to his old workplace and constantly visits the office during working hours, eventually resulting in Neil banning him from the premises. He earns additional income on the side from Z-list celebrity appearances at various club nights trading on the minor fame the documentary series has given him, but he is frequently met with heckles and abuse from the crowds and gradually hits an emotional low. He is allowed to attend the Wernham Hogg Christmas party that ends the special, at which he meets a blind date who genuinely enjoys his company and says she would go out with him again. In higher spirits, Brent is later shown bonding with his former colleagues and finally succeeds in making them laugh when they take a group photo together.

In 2002, Gervais wrote an in-character piece for the BBC website on "what makes a winner" of the FA Cup. He said, "Managing a Premiership football team is a bit like running a successful paper merchant. There's a lot of similarities. I have to pick the right team, I have to lead by example, I have to instil trust and discipline."
