Portrayed By: Kyra Sedgwick

Deputy Chief Brenda Leigh Johnson is a hard-nosed, take-no-prisoners detective who heads the Major Crimes Division of the Los Angeles Police Department. She's tough, smart, and determined, and she'll do whatever it takes to get her man. But her abrasive personality often rubs people the wrong way, and she's made more than her fair share of enemies. But even her detractors can't deny her skills as a detective. She's a master at getting confessions, and she's closed more cases than anyone else in the department. She's a closer, and she's the best in the business.
