Whittaker, who rose to fame with ITV's crime drama "Broadchurch", will be playing the 13th Doctor in the BBC1 drama, reported the Guardian.
"I'm beyond excited to begin this epic journey - with Chris and with every Whovian on this planet. It's more than an honour to play the Doctor. It means remembering everyone I used to be, while stepping forward to embrace everything the Doctor stands for: hope. I can't wait," Whittaker said.
Colin Baker, the sixth actor to play the role, from 1984-86, applauded the decision of the makers.
Arthur Darvill, who portrayed the character of Rory Williams on "Doctor Who", simply wrote, "Yes Jodie".
