The promo video sees the Cullens gather together various vampire clans to protect Edward and Bella's daughter Renesmee from the Volturi, led by Michael Sheen's sinister villain Aro.
The Breaking Dawn teaser arrives to coincide with the 111th birthday of Stephenie Meyers's Twilight protagonist Edward Cullen.
Lionsgate executive Rob Friedman recently denied speculation that the studio has plans in place to reboot the series after the release of Breaking Dawn - Part 2 later this year.
He said: "We are not remaking Twilight. We will happily support Stephenie Meyer if she decides to proceed in any way. But this will be the last one, unless that should change."
The Twilight Saga: Breaking Dawn - Part 2 will open in cinemas on November 16.
