when does Amy leave in West Wing

Amy Gardner leaves The West Wing in the season 5 episode “Constituency of One” ; that’s her last appearance before she later returns near the end of the series.

What that means

• She had been a recurring character since season 3, played by Mary-Louise Parker.

• Her exit from the main run is tied to that fifth-season episode, not an early-season breakup moment.

• Some viewers remember her relationship fallout with Josh happening earlier, but her actual last appearance is later.

Tiny context

Amy is one of those characters whose presence lingers even after she steps away, so the show makes her feel “gone” before she is formally absent. That’s why fan discussions often point to different episodes depending on whether they mean the breakup, the firing, or the final departure.

Answer in one line

She leaves in Season 5, Episode 5, “Constituency of One.”
