The ten-second video gives fans a new glimpse at the final instalment in Stephenie Meyer's series, which sees Kristen Stewart's Bella transformed into a vampire and fighting to protect her newborn daughter Renesmee.
The full teaser trailer will premiere tomorrow (June 20) at 5.30am PDT / 8.30am EDT / 1.30pm BST. Lionsgate and Summit Entertainment are releasing the promo to coincide with Edward Cullen's 111th birthday.
Lionsgate executive Rob Friedman recently denied rumours that the studio was considering rebooting the series.
"We are not remaking Twilight," Friedman said. "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.
