The singer posted the cover - which appears below - for her forthcoming track 'Girl On Fire' via Instagram.
She tweeted: "Crazy excited!!! My new single #GirlOnFire will be unleashed soon!!! Are you ready? ;-)"
'Girl On Fire' serves as the lead single from her album of the same name, which is out November 26 and a day later in the US.
Previously speaking about her new album, Keys said: "Girl on Fire is about new beginnings, new perspectives and fresh starts... stripping away all the bad energy in your life and taking full control of the reins and how you want to live."
The star will unveil the song with a performance at the MTV VMAs in Los Angeles on September 6.
Meanwhile, Keys recently teamed up with Dr Dre and 50 Cent for new track 'New Day', but it has not been confirmed whether the cut will feature on Girl on Fire.
