Who Is JJ on Criminal Minds

Jennifer "JJ" Jareau, commonly known as JJ, is a Supervisory Special Agent and experienced media liaison on Criminal Minds. Portrayed by A.J. Cook, JJ serves as a bridge between the BAU and the press, communicating complex behavioral analysis to the public. Her character is defined by her empathy, professionalism, and long-standing partnership with the team. Over the series’ run, JJ’s personal life, including her marriage and children, has been an ongoing subplot that humanizes her high-stress role within the FBI’s Behavioral Analysis Unit.

JJ’s Family on the Show

Marriage to William LaMontagne Jr.

On Criminal Minds, JJ is married to William LaMontagne Jr., a detective. Their relationship is portrayed as supportive and enduring, despite geographic distance and demanding careers. William appears across multiple seasons, demonstrating loyalty and involvement in JJ’s professional challenges. Their partnership reflects the show’s recurring theme of balancing personal commitments with high-risk law enforcement work.

Children: Henry and Josie LaMontagne

JJ and William have two children: a son named Henry LaMontagne and a daughter named Josie LaMontagne. Henry appears in several episodes, showing the dynamics of a close-knit family. Josie is mentioned periodically, often in dialogue about parenting, birthdays, and school events. The show uses these family moments to provide contrast to the intense cases the BAU investigates, grounding JJ’s character in relatable domestic responsibilities.

Public Portrayal vs. Real Life

It is important to distinguish the fictional family of JJ on Criminal Minds from the personal lives of the cast. On screen, Henry and Josie are central to JJ’s storyline; off screen, A.J. Cook has her own family unrelated to the show’s plot. Viewer understanding of this separation helps avoid confusion about what is dramatized for television and what exists in the actor’s real-world context. The show’s writers periodically reference her children to reinforce her character’s development, but these elements are part of the scripted narrative, not biographical details of the performer.

Appearances and Storylines Involving Henry

Henry LaMontagne appears in episodes spanning multiple seasons, often during family-centric storylines or holidays. These scenes highlight JJ’s role as a mother and the challenges of maintaining stability while supporting demanding careers. Specific episodes feature parenting milestones, such as birthdays and school events, which serve as narrative anchors amid the series’ darker crime drama arcs.
