Catherine Willows (née Flynn) is a fictional character on the CBS crime drama CSI: Crime Scene Investigation, portrayed by Marg Helgenberger, who has received two Emmy nominations and two Golden Globe nominations for the role. Catherine Willows is employed as a crime-scene investigator supervisor (a "CSI-3") and forensic scientist for Clark County, Nevada, which contains the city of Las Vegas until the middle of Season 12, when she accepts a job at the FBI.

Catherine appears in every episode up to "Willows in the Wind" (Season 12: episode 12), with the exceptions of "Random Acts of Violence" from season three, "Hollywood Brass" and "Committed" from season five, and "House of Hoarders," "All That Cremains," and "Unleashed" from season eleven.

Helgenberger discussed her upcoming departure from CSI on the January 18, 2012, The Late Show with David Letterman, a week before that episode would air.

Catherine Willows was raised by her single mother, Lily Flynn, a cocktail waitress and showgirl. Due to the nature of her mother's jobs, Catherine was constantly moved around the west coast of America as a child and because of this, she found it difficult to settle in school. Consequently, she failed to excel to her full potential in school, despite her high intelligence and razor-sharp mind. Catherine left school and began work as an exotic dancer in order to support her boyfriend's music career. She became interested in police work when she befriended a regular at the dance club; Detective Tadero, who also encouraged her to return to school. She attended West Las Vegas University, where she graduated with a degree in Medical Science. Catherine joined the CSI team at LVPD as a lab technician, after which she worked her way up to the role of supervisor under the watchful eye of Gil Grissom.

Catherine Willows has not been a contender in any CBUB matches.
