Glenn Quagmire (born Glenn Quagglechek) is the sex-crazed, perverted neighbor of the Griffins on Family Guy. Quagmire is a former ensign of the U.S. Navy, where he met Peter Griffin. He currently works as an airline pilot.

In "The Unbrave One", Francine takes an online pregnancy test from one "Dr. Vadgers". It is obviously a scam, but only Stan can see that. During the credits, a house is seen with lots of typing heard from inside. In the last few seconds, a close-up on a pair of hands is shown typing an e-mail signed Dr. Vadgers. It revealed to be Glenn Quagmire, who says his catch phrase, "Giggity."

Quagmire is voiced by Seth MacFarlane.
