The name was revealed today (November 3) at the launch press conference for Daniel Craig's third outing as Ian Fleming's secret agent.
The new 007 movie will see Craig star alongside a returning Judi Dench and franchise newcomers Javier Bardem, Ralph Fiennes and Albert Finney.
Craig said that the film will be "Bond with a capital 'B'", adding: "It's all in the script and we've got a great script."
Bérénice Marlohe will play a character called Severin in the film, who she described as
"glamourous" and "enigmatic". Naomie Harris will play a field agent called Eve.
The movie will not relate to an original Fleming story, but the title "has some emotional context which will be revealed in the film".
Oscar-winning American Beauty director Sam Mendes will direct Skyfall from a script by John Logan, Neal Purvis and Robert Wade.
"I thought the story was fantastic," Mendes said. "I love Daniel and Judi. This is an enormous challenge."
He added that Skyfall "is its own story" and "doesn't connect with the last two movies".
Barbara Broccoli and Michael G Wilson will again serve as producers.
Despite various rumours of who might record the Skyfall theme - including Kings of Leon and Adele - it was revealed that various artists are being considered but none were confirmed.
Craig's previous James Bond films - Casino Royale and Quantum of Solace - have grossed more than $1 billion (£625 million) at the worldwide box office.
Skyfall will be released in cinemas on October 26, 2012.
