Most Unforgettable TV Cliffhangers That Left Fans Stunned

The concept of the television cliffhanger dates back to the late 1970s. It began with ABC’s Soap, a parody of daytime soap operas that delivered one of the first major TV cliffhangers.

Over the decades, cliffhangers have been refined across every genre of television. The best ones break out of their shows’ fan bases and become part of popular culture.

Below are some of the greatest television cliffhangers of all time.

Note: We applied one rule — one show, one cliffhanger. Series finales were excluded because they serve as definitive endings rather than lingering cliffhangers.

30. Dynasty: The Moldavian Massacre

Warning: This content contains spoilers.

Episode: “Royal Wedding” (Season 5, Episode 29)

Air date: May 15, 1985

Starring: John Forsythe, Linda Evans, John James, Heather Locklear, Emma Sams, Joan Collins, Diahann Carroll, Ali Macgraw

Bottom line: In the wake of Dallas’s “Who Shot J.R.?” obsession, Dynasty delivered its own sensational finale known as “The Moldavian Massacre.” The closing image of wedding guests piled atop one another after an attack became an iconic, if chaotic, cliffhanger of 1980s nighttime soap opera melodrama.

29. Heroes: You Saved the Cheerleader

Episode: “How To Stop An Exploding Man” (Season 1, Episode 23)

Air date: May 21, 2007

Starring: Milo Ventimiglia, Hayden Panettiere, Masi Oka, Zachary Quinto, Jack Coleman, Adrian Pasdar, Ali Larter, Leonard Roberts, Greg Grunberg

Bottom line: Heroes’ first season became a cultural phenomenon. The finale delivers two unforgettable cliffhangers: Nathan Petrelli flying his brother Peter into the sky culminating in a massive explosion, and Hiro Nakamura materializing in feudal Japan. Both moments highlighted how potent season-long storytelling can be.

28. 24: Jack Takes the Slow Boat to China

Episode: “Day 5: 6:00 a.m-7:00 a.m.” (Season 5, Episode 24)

Air date: May 22, 2008

Starring: Kiefer Sutherland, Mary Lynn Rajskub, Kim Raver, Jean Smart, Gregory Itzin, James Morrison

Bottom line: Season five of 24 is often cited as the series high point. The finale leaves Jack Bauer beaten and missing, last seen aboard a tanker bound for China as punishment by Chang Zhi. It’s a bleak, relentless cliffhanger befitting the show’s tension-fueled format.

Episode: “A Leap For Lisa” (Season 4, Episode 22)

Air date: May 20, 1992

Episode: “The Phantom” (Season 5, Episode 13)

Air date: June 10, 2012

Starring: Jon Hamm, John Slattery, Elisabeth Moss, Vincent Kartheiser, Christina Hendricks, Alison Brie, Alexis Bledel, Julia Ormond, Jessica Paré

Bottom line: Many point to Don Draper’s impulsive marriage at the end of season four as Mad Men’s big turn, but season five’s finale carries an equal sting.
