Diane Fowler was a character in the NBC series The Blacklist.
At her initial meeting with Harold Cooper regarding Raymond Reddington, she is very resistant that Red should receive an immunity deal. It is only after the train wreck, that she reluctantly agrees to sign off on Red's deal. As she signs, she says to Cooper that one day the 2 of them will be talking about this in front of a Senate Committee. She agrees with Cooper that Dembe Zuma and Luli Zeng are the least offensive of Red's suggested security detail, and adds that she wants Meera Malik on the team as her personal representative.
When Red was kidnapped by Anslo Garrick, Fowler was enraged and disbanded the task force. Part of the reason was that she knew the FBI had a double agent within the ranks. She later reactivated it when it was discovered that the people behind the raid had been conducting surveillance on the FBI. She orders Harold Cooper to locate Raymond Reddington since she thinks he knows who has infiltrated the FBI.
Along with Harold Cooper, she watches the questioning of Elizabeth Keen, Donald Ressler, Meera Malik, and Aram Mojtabai. Despite pressure from Alan Fitch, while at the Office of the Director of National Intelligence (ODNI), she refuses to reveal information concerning Red and the recent internal investigation.
Red meets with her after learning she is the real mole. Fowler first attempts to bargain with Red and then resorts to threats, but Red knows her death will not lead to further retaliation from Alan Fitch. When she offers to tell Red what happened to his family, he merely remarks that if she knows what happened then someone else out there knows it too. Red then shoots and kills her and calls Kathryn Nemec to clean up and dispose of the body.
Fowler's body is found.
Diane is shown in a flashback being killed by Reddington. She is implied to have been one of those to have learned that Raymond Reddington is not actually Raymond Reddington and was killed to cover up his secrets.
