David Sinclair is a fictional character in the CBS crime drama Numb3rs, played by Alimi Ballard. First introduced in the pilot episode, he has become the usual partner of FBI Special Agent Colby Granger (Dylan Bruno) and has also become the primary relief supervisor for the Supervisor of the FBI Violent Crimes squad, Don Eppes (Rob Morrow). At first unpopular with critics, Sinclair has since been recognized as a popular character on the show.

Since Season 2, Sinclair is usually partnered with Colby Granger and tried to stick up for him in "The Mole". In fact, in the Season 3 finale, "The Janus List", when Colby is revealed to be a double agent working as a spy for the Chinese, David reacted with deep pain and blind fury at the betrayal, tears welling in his eyes during Colby's confession just before he attempted to assault Colby in the interrogation room of the L.A. office. Even with the possibility of Colby having been a triple agent and the will to save him, David is not ready to see his partner yet, as he feels he does not really know him. Alan Eppes has given him something to think about, as Mr. Eppes had said this is a test of true friendship and that he must try to understand his motives. The two are close once more, but only after many failures to cooperate on a mission.

David was assigned to work with Don Eppes in the pilot episode, by the assistant director. By Season 3, he has been with Don three years, and there is nothing Don can not ask David to do, though, Don worries David may one day realize he has seen too much and leave the FBI. He has knowledge of bomb disposal due to his first posting overseas in Tel Aviv, Israel. In addition, David did some work for the Long Beach FBI office.

David carries a Glock 22 pistol.
