List of Appearances

Alexandra "Alex" Quinn is an NCIS Special Agent formerly attached to the Federal Law Enforcement Training Center (FLETC) and who for a year served as a member of the main NCIS Major Case Response Team led by NCIS Special Agent Leroy Jethro Gibbs before ultimately resigning from the team for good presumably some time prior to September 2017 to take care of her mother who had developed Alzheimer's.



NCIS Season 14

Quinn while talking to Gibbs. From the NCIS Season 14 premiere episode, "Rogue".

Quinn made her debut appearance in the NCIS Season 14 premiere episode, "Rogue" where she arrived in the bullpen while sarcastically congratulating Gibbs on the fact he'd set a new record by rejecting eight new agents over the last three months.



Quinn is a woman in her mid forties with tanned skin, curly brown hair with blonde highlights and brown eyes.

Like NCIS Senior Special Agent Timothy McGee and NCIS Probationary Agent Eleanor Bishop, Quinn wears her watch on her right wrist.

She also wears a ring on the second last finger of her right hand and a necklace around her neck.



  • She is the only cast member to be part of the main cast for one season.
