Leroy Jethro Gibbs from NCIS is written as having attended Marine Corps sniper school and various military-related trainings, but the show never clearly establishes a traditional civilian college he attended.

Because of that, most fan and forum discussions conclude that:

  • There is no canon statement like “Gibbs went to X University” in the series.
  • His background is focused on being a Marine, a sniper, and later an NCIS agent, not on a named college degree.

So if your question “where did Gibbs go to college” refers to NCIS’s Leroy Jethro Gibbs, the honest answer is: the show does not confirm any specific college, only his Marine and professional training path.
