Pattinson chose an eye-catching dark green suit for the premiere, while Lautner dressed in grey and Stewart wore a revealing pale dress with lace detail.
Guests including Stevie Nicks, Goran Visnjic and Elle Fanning also walked the movie's 'black carpet' on Monday evening in Los Angeles.
A 'Twilight Village' has been established around the sports arena as fans gather to catch a glimpse of Stewart, Pattinson and Lautner at the premiere.
The Staples Center, home to the Los Angeles Lakers, sits adjacent to red carpet venue the Nokia Theatre.
Twilight star Lautner, who plays werewolf Jacob Black, has said that the saga coming to an end is "bittersweet" for him.
"This character, this franchise, it's been such a huge part of my life that I don't even know what it's going to feel like when it's all said and done," he said.
"It's a strange feeling and it's bittersweet because I have a special place for Jacob, for Twilight and all of those memories, but it's exciting to start the next chapter."
