Colby Granger is a fictional character in the CBS crime drama Numb3rs, played by Dylan Bruno. First introduced during the second season, he has become a part of the team led by FBI Special Agent Don Eppes (Rob Morrow) and is usually partnered with David Sinclair. This connection creates some tension when Colby is accused of being a spy for the Chinese which is confirmed in the season three finale episode, "The Janus List", with the news leaving the FBI team under Don's command shaken by the revelation.

Colby was introduced in the second season of the TV show Numb3rs as a rookie Federal Bureau of Investigation agent. David Sinclair is his usual partner. Granger idolizes the legendary sniper/tracker Agent Ian Edgerton.

Having previously used the SIG Sauer P226, Granger had recently begun carrying the .45 ACP caliber Springfield Armory Custom TRP (Tactical Response Pistol) Professional Model, which indicates he is SWAT/HRT qualified, as only SWAT/HRT qualified FBI agents are authorized to carry that weapon on duty. This is proven to be true in the Season 4 episode, "Chinese Box" as he helps SWAT in the rescue operation to save David who is being held hostage in an elevator by a gunman. Granger later switches to the Smith & Wesson PC 945.

As new partners in season 2, David and Colby seemed to disagree with each other on methods used while working on cases. For the first few episodes, they did not seem to like each other at all. Over time, however, they became very close friends.
