The actor posted a filtered selfie – only featuring the top part of his face – with the words “my name’s Elba, Idris Elba”.
New rumours emerged this week amid reports that Bond producer Barbara Broccoli said it was now “time” for a black actor to take the role.
Elba, 45, has previously said he thought he might be too old to play the legendary secret agent.
Twitter reacted to his post with a host of memes, including a photoshopped President Trump holding up a picture of Elba and announcing him as the new Bond, and a proud looking Sean Connery punching the air.
All eyes will now be on Elba, but what about the other likely candidates for the famous role?
Who has a licence to kill?
Bond made his first appearance in spy novel Casino Royale in 1952, and quickly become author Ian Fleming’s most famous creation.
Production on the 25th Bond film, led by Oscar-winning director Danny Boyle, will begin in December.
The as-yet unnamed film, understood to be Daniel Craig’s final appearance in the role, is due to be released in 2019.
