Gravity Falls ended on February 15, 2016, with the one-hour series finale “Weirdmageddon 3: Take Back the Falls.”

Quick Scoop: When did Gravity Falls end?

  • The final episode of Gravity Falls aired on Disney XD on February 15, 2016.
  • It was a special one-hour finale titled “Weirdmageddon 3: Take Back the Falls.”
  • Episode guides list the show’s overall end date as February 2016 , matching the finale broadcast.

A tiny bit of story context

The finale wraps up the big “Weirdmageddon” arc, where Dipper, Mabel, and the rest of the Pines family face Bill Cipher in a last stand for Gravity Falls. It’s designed as a true ending to the mystery summer rather than a cliffhanger, which is why the show stops after season 2.

Why it ended then (not canceled mid-way)

  • Creator Alex Hirsch planned Gravity Falls as a finite, two-season story about one epic, weird summer.
  • He announced in November 2015 that the series would conclude with the season 2 finale, clarifying it was “ending, not being canceled.”
  • Because of that, the February 15, 2016 air date is considered the intentional, planned end of the series.

Is there any “latest news” after the ending?

  • The core TV series still ends in 2016, with no season 3 announced.
  • The story has continued in books and tie-in media like Journal 3 (2016), the graphic novel Gravity Falls: Lost Legends (2018), and the teen novel The Book of Bill (2024).
  • Hirsch has said he’s open to more specials someday, but nothing has changed the fact that the show itself ended on February 15, 2016.

TL;DR: If you’re binging and wondering “when did Gravity Falls end,” the official series finale aired on February 15, 2016, and everything after that is extra lore in books and side media—not new seasons.
